Monitoring MySQL backups is a vital part of any reliable backup solution. By monitoring the most common disaster recovery metrics, the Recovery Time Objective and the Recovery Point Objective, you can find out if a backup job was successful and produced a usable backup copy. The TwinDB Backup Tool along with Datadog allows monitoring both […]

The post Monitoring MySQL Backups With Datadog and TwinDB Backup Tool appeared first on TwinDB.

There are 3 pillars for a database architecture: Monitoring, Backup / Restore process, High Availability This blog post is about database High Availability; more precisely about one of the best combo of the moment : MySQL 5.7 Group Replication : the only native HA solution for MySQL, it's a Single/Multi-master update everywhere replication plugin for MySQL with built-in automatic distributed recovery, conflict detection and group membership. ProxySQL 1.4 : probably the best proxy for MySQL.

In this blog post, we’ll look at Percona Monitoring and Management’s pmm-admin list command.

The pmm-admin list command shows all monitoring services you have added using the pmm-admin add command. Starting with version 1.4.0, Percona Monitoring and Management (PMM) also lists external monitoring services when you run pmm-admin list, i.e., those services that monitor the backends not supported out of the box (such as PostgreSQL databases).

In the output, the external monitoring services appear at the bottom:

MySQL 8.0.1 introduced a work with replication threads mutexes in order to improve performance. In MySQL 8.0.2 the same work was extended, focusing in usability, and revamped how replication deals with disk-full conditions, improving the responsiveness of both monitoring commands and administrative commands such as KILL, as well as making status messages much more precise and helpful.…

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, …

Percona 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:

In this blog post, I will demonstrate how to run and use sysbench histograms.

One of the features of sysbench that I often I see overlooked (and rarely used) is its ability to produce detailed query response time histograms in addition to computing percentile numbers. Looking at histograms together with throughput or latency over time provides many additional insights into query performance.

Here is how you get detailed sysbench histograms and performance over time:

sysbench --rand-type=uniform --report-interval=1 --percentile=99 --time=300 --histogram --mysql-password=sbtest oltp_point_select --table_size=400000000 run

There are a few command line options to consider:

• report-interval=1 – prints out the current performance measurements every second, which helps see if …

Welcome to another post in our series of interview blogs for the upcoming Percona Live Europe 2017 in Dublin. This series highlights a number of talks that will be at the conference and gives a short preview of what attendees can expect to learn from the presenter.

This blog post is with Bernd Erk, CEO of Icinga. His talk is titled Monitoring Open Source Databases with Icinga. Icinga is a popular open source successor of Nagios that checks hosts and services, and notifies you of their statuses. But you also need metrics for performance and growth to deal with your scaling needs. Adding conditional behaviors …
