Webinar Wednesday, October 11, 2017: Percona Monitoring and Management (PMM) Demonstration

Percona Monitoring and Management

Percona Monitoring and Management (PMM)Join Percona’s Product Manager Michael Coburn as he presents a Percona Monitoring and Management (PMM) Demonstration on Wednesday, October 11, 2017, at 10:00 am PDT / 1:00 pm EDT (UTC-7).

How can you optimize database performance if you can’t see what’s happening? Percona Monitoring and Management (PMM) is a free, open source database troubleshooting and performance optimization platform for MySQL and MongoDB. PMM uses Metrics Monitor (Grafana + Prometheus) for visualization of data points. It also has Query Analytics (QAN), to help identify and quantify non-performant queries and provide thorough time-based analysis to ensure that your data works as efficiently as possible.

Michael Coburn will provide a brief demo of PMM. He will also cover newly released features in PMM such as QAN for MongoDB, new MyRocks dashboards and tooltips for metrics monitoring.

By the end of the webinar you will have a better understanding of how to:

  • Observe database performance from a system and service metrics perspective
  • See database performance from the queries executing in MySQL and MongoDB
  • Leverage the metrics and queries from PMM to make informed decisions about crucial database resources: scaling your database tier, database resource utilization and management, and having your team focus on the most critical database events

Register for the webinar here.

Michael CoburnMichael Coburn, Principal Technical Account Manager

Michael joined Percona as a Consultant in 2012. He progressed through various roles including Managing Consultant, Principal Architect, Technical Account Manager, and Technical Support Engineer. He is now leading Product Management for Percona Monitoring and Management.

MyRocks Metrics Now in PMM 1.3.0

MyRocks

One of the most exciting features shipped in the Percona Monitoring and Management 1.3.0 (PMM) release is support for MyRocks metrics via a new Metrics Monitor dashboard titled MySQL MyRocks Metrics. The support in PMM follows the recent Percona Server for MySQL release 5.7.19 from September 6, where Percona delivered an EXPERIMENTAL version of MyRocks for non-Production usage.

The MyRocks storage engine from Facebook is based on RocksDB, a persistent key-value store for fast storage environments. MyRocks is optimized for fast storage and combines outstanding space and write efficiency with acceptable read performance. As a result, MyRocks has the following advantages compared to other storage engines (if your workload uses fast storage, such as SSD):

  • Requires less storage space
  • Provides more storage endurance
  • Ensures better IO capacity

MyRocks Database Operations

This graph will help you visualize MyRocks database operations of Next and Seek attributes:

MyRocks Cache Activity

We also have a graph to help you visualize the count of Hits and Misses on the MyRocks cache:

MyRocks Cache Data Bytes Read/Write

Finally, another important MyRocks graph will help you understand the volume of data read and written to the MyRocks cache:

Please note that the MyRocks storage engine is not suitable (yet) for production workloads, but if you are testing this technology take a moment to install PMM in order to take advantage of our new MySQL MyRocks Metrics dashboard!

In PMM, you can view the metrics provided by the information schema as well as various data reported by the RocksDB engine’s status used by your MySQL database instance.

Percona Monitoring and Management 1.3.0 Is Now Available

Percona Monitoring and Management 1.3.0

Percona Monitoring and Management 1.3.0Percona announces the release of Percona Monitoring and Management 1.3.0 on September 26, 2017.

Percona Monitoring and Management 1.3.0 introduces basic support for the MyRocks storage engine. There is a special dashboard in Metrics Monitor that presents the essential metrics of MyRocks as separate graphs. Also, Metrics Monitor graphs now feature on-demand descriptions that remain visible as long as hover over them.

For example, this graph helps you visualize MyRocks database operations of Next and Seek attributes:

There are many improvements to QAN (Query Analytics) both in the user interface design and in its capabilities. In this release, QAN starts supporting all types of MongoDB queries. For example, if you need to limit the list of available queries to only those that you are interested in, use the Query Filter field next to the database selection button:

Orchestrator is not enabled by default because leaving it in a non-configured state was confusing to users. It is still possible to enable it along with the docker run command.

For install and upgrade instructions, see Deploying Percona Monitoring and Management.

New Features

  • PMM-1290: Basic support for the metrics of the MyRocks storage engine in MySQL via the mysqld-exporter.
  • PMM-1312: Metrics Monitor now features a MyRocks dashboard.
  • PMM-1330: Basic telemetry data are collected from PMM Servers.
  • PMM-1417: A new dashboard in Metrics Monitor designed to enable exploring any data in Prometheus
  • PMM-1437pmm-admin allows passing parameters to exporters
  • PMM-685: The EXPLAIN command is now supported in QAN.

Improvements

  • PMM-1262: The system checks for updates much faster
  • PMM-1015QAN should shows all collections from a mongod instance. Make sure that profiling is enabled in MongoDB.
  • PMM-1057QAN supports all MongoDB query types.
  • PMM-1270: In Metrics Monitor, the dashboard filter displays only MariaDB hosts.
  • PMM-1287: In pmm-admin mongodb:queries is not experimental anymore and the dev-enable option is no longer needed.
  • PMM-1446: In Metrics Monitor, the MySQL Active Threads graph displays data more accurately.
  • PMM-1455: In Metrics Monitor, features descriptions of graphs
  • PMM-1476: QAN2 is used by default in pmmdemo.percona.com
  • PMM-1479: It is now possible to go to QAN directly from Metrics Monitor.
  • PMM-515Orchestrator is disabled by default. It is possible to enable it when running your docker container.

Bug fixes

  • PMM-1298: In QAN, the query abstract could be empty for MySQL hosts for low-ranking queries. This bug is fixed to contain Low Ranking Queries as the value of the query abstract.
  • PMM-1314: The selected time range in QAN could be applied incorrectly. This bug is now fixed.
  • PMM-1398: Prometheus memory was not updated after PMM upgrade. This bug is now fixed.
  • PMM-1427: The CPU Usage/Load graph in the MySQL Overview dashboard was displayed with slightly incorrect dimensions. This bug is now solved.
  • PMM-1439: If the EXPLAIN command was not supported for the selected query, there could appear a JavaScript error.
  • PMM-1472: It could happen that monitoring of queries for MongoDB with replication could not be enabled.
  • PMM-943: InnoDB AHI Usage Graph had incorrect naming and hit ratio computation.

This Week in Data with Colin Charles #5: db tech showcase and Percona Live Europe

Percona Live Europe 2017 in Dublin

Have you registered for Percona Live Europe Dublin? We have announced some awesome keynotes, and our sponsor list is growing (and we’re always looking for more!).

There will also be a community dinner (Tuesday, September 26, 2017), so definitely watch the announcement that will be on the blog, and I’m sure on Twitter. Besides being fun, the Lightning Talks will happen during that time.

Releases

Link List

db tech showcase Tokyo, Japan

The annual db tech showcase Tokyo 2017 took place this week from 5-7 September. It was a fun event as always, with capacity for 800 people per day. The event grows larger each year, and reminds me of the heyday of the MySQL Conference & Expo.

The db tech showcase is a five-parallel-track show, with each talk approximately 50 minutes. The event started with a keynote by Richard Hipp, creator of SQLite (if you were a Percona Live Santa Clara 2017 attendee, you’d have also seen him there). The rest of the event is a mix between Japanese language content and English language content. The sponsor list is lengthy, and if you walk the floor you could collect a lot of datasheets.

One thing I really liked? At some talks, you’d get a clear folder with a contact form as well as the printed slide deck. This is a great way to let the speaker’s company contact you. It’s a common issue that I (and others) speak to large amounts of people and have no idea who’s in the talk. I can only imagine our marketing and sales teams being much happier if they could get access to an attendee list! I wonder if this will work in other markets?

It’s interesting to see that there is a Japan MariaDB User Group now. It’s clear the MySQL user group needs a revival! I saw a talk from Toshiba on performance tests using MariaDB Server, but not with MySQL (a little odd?). The MongoDB content was pretty latent, which is unsurprising because we don’t see a huge MongoDB uptake or community in Japan (or South Korea for that matter).

Will I go back? Absolutely. I’ve been going for a few years, and it’s a great place for people who are crazy about database technology. You really get a spectrum of database presentations, and I expect most people go back with many ideas of what they might want to evaluate for production.

I spoke about the Engineering that goes into Percona Server for MySQL 5.6 and 5.7, with a hint of MongoDB. The slides are in a mix of Japanese and English. The Japanese translation: Percona Server?MySQL 5.6?5.7????????????????MongoDB?????.

Upcoming Appearances

Percona’s website keeps track of community events, so check there to see where to listen to a Perconian speak. My upcoming appearances are:

Feedback

Did you try replication-manager last week? Guillaume Lefranc, the lead developer, writes in to talk about the new features such as support for MySQL 5.7, Binlog Flashback, multi-cluster mode and various stability fixes.

MyRocks Experimental Now Available with Percona Server for MySQL 5.7.19-17

MyRocks with Percona Server for MySQL

MyRocks with Percona Server for MySQLPercona, in collaboration with Facebook, is proud to announce the first experimental release of MyRocks in Percona Server for MySQL 5.7, with packages.

Back in October of 2016, Peter Zaitsev announced that we were going to port MyRocks from Facebook MySQL to Percona Server for MySQL.

Then in April 2017, Vadim Tkachenko announced the availability of experimental builds of Percona Server for MySQL with the MyRocks storage engine.

Now in September 2017, we are pleased to announce the first full experimental release of MyRocks with packages for Percona Server for MySQL 5.7.19-17.

The basis of the MyRocks storage engine is the RocksDB key-value store, which is a log-structured merge-tree (or LSM). It uses much less space, and has a much smaller write volume (write amplification) compared to a B+ tree database implementation such as InnoDB. As a result, MyRocks has the following advantages compared to other storage engines, if your workload uses fast storage (such as SSD):

  • Requires less storage space
  • Provides more storage endurance
  • Ensures better IO capacity

Percona MyRocks is distributed as a separate package that can be enabled as a plugin for Percona Server for MySQL 5.7.19-17.

WARNING: Percona MyRocks is currently considered experimental and is not yet recommended for production use.

We are providing packages for most popular 64-bit Linux distributions:

  • Debian 8 (“jessie”)
  • Debian 9 (“stretch”)
  • Ubuntu 14.04 LTS (Trusty Tahr)
  • Ubuntu 16.04 LTS (Xenial Xerus)
  • Ubuntu 16.10 (Yakkety Yak)
  • Ubuntu 17.04 (Zesty Zapus)
  • Red Hat Enterprise Linux or CentOS 6 (Santiago)
  • Red Hat Enterprise Linux or CentOS 7 (Maipo)

Installation instructions can be found here.

Due to the differences between Facebook MySQL 5.6.35 and Percona Server for MySQL 5.7, there are some behavioral differences and additional limitations. Some of these are documented here.

We encourage you to install and experiment with MyRocks for Percona Server for MySQL and join the discussion here.

Any issues that you might find can be searched for and reported here.

We thank the RocksDB and MyRocks development teams at Facebook for providing the foundation and assistance in developing MyRocks for Percona Server for MySQL. Without their efforts, this would not have been possible.

This Week in Data with Colin Charles #4: Percona Server for MySQL with MyRocks

Colin Charles

Join Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.

Colin CharlesPercona Live Europe Dublin

Have you registered for Percona Live Europe Dublin? We’ve more or less finalized the schedule, and the conference grid looks 100% full. We’re four weeks away, so I suggest you register ASAP!

I should also mention that no event can be pulled off without sponsors, so thank you sponsors of Percona Live Europe 2017. I sincerely hope to see more sign up. Feel free to ask me more about it, or just check out our sponsor prospectus.

Releases

  • MariaDB/MySQL Replication Manager 1.1.1 release. There was recently a talk accepted at Percona Live Europe 2017 that referenced “MRM”. I was asked about it, and I think this tool needs more marketing! MRM is a high availability solution to manage MariaDB 10.x and MySQL and Percona Server for MySQL 5.7 GTID replication topologies. It has a new 1.1.1 release that provides improvements for MariaDB Server and MariaDB MaxScale (this tool itself gained MySQL GTID support back in April 2017). Do you use MRM?
  • Colin CharlesPercona Server 5.7.19-17 is now released! Why is this exciting? Because it comes with the MyRocks storage engine! Yes, the engine is experimental, and no, it isn’t recommended for production – but why not get started with the MyRocks Introduction? I tried the installation guide and got everything started very quickly. Read about the current limitations and differences between Percona MyRocks and Facebook MyRocks (considering you’ll really want to use MyRocks in a shipping release – Facebook’s MyRocks requires compiling their tree, and this is really not the recommended way to get going!).

This Week in Data: Thoughts from Percona Chief Evangelist Colin Charles

Colin Charles

Colin CharlesWelcome to a new weekly column on the Percona blog. My name is Colin Charles, Percona Chief Evangelist, and I have been involved in MySQL, MariaDB Server and the open source community for over a decade. Now I am at Percona, and this is my weekly column.

When you start a column, you have ask yourself what you’ll be writing about. Keeping the focus on the reader is what’s crucial. With this in mind, I plan to cover happenings, pointers and maybe even musings in this column. It’s August, and while many are away on summer vacations, there’s still plenty happening in the database world. So maybe this will be a little like the now-defunct, Weekly MySQL News. It will be broader than just MySQL, however, and focus on open source databases (after all, Percona’s mission is to to champion unbiased open source database solutions).

So let’s get started! I look forward to feedback/tips via comments, or you can email me directly at colin.charles@percona.com. Feel free to socialize with me! I’m @bytebot on Twitter.

Percona Live Europe Dublin

Percona Live Open Source Database Conference Europe 2017 started in London, moved to Amsterdam (where last year it sold out at 400+ attendees) and is now docking itself in Dublin. Dublin, famous for Guinness, is also now famous a European tech hub. With our expanded conference focus beyond just the MySQL ecosystem, Percona Live Europe also includes MongoDB, PostgreSQL and other open source databases.

Where are we at with the event? The sneak peak schedule is out, and we aim to have a more or less full conference schedule by the second week of August. The conference committee is at its most diverse, with two MongoDB Masters to ensure tighter content around MongoDB, and also two whom are prominent in the DevOps world.

Naturally, evolution is good because you are now getting the “best of the best” talks, as there are less slots to compete when it comes to topics! Registration is open, and you’ll want to sign up as soon as possible to lock in the best available rates.

Percona Live Europe in Dublin is also a great place to be a sponsor as a smaller, intimate event helps ensure that people pop by your expo hall booths. This is great for promoting your products, hiring new folks and so on. Find out more about sponsorship here.
