PMM 2Where we are today

What's New and Exciting?

● Query Analytics○ Support for large environments○ Filtering using query metadata and labels○ Sorting and additional columns○ Support for PostgreSQL

● pmm-agent● Standard and Custom labels● Inventory Overview● Multiple scraping intervals

Support for Large Environments

● MySQL out - ClickHouse in● Columnar datastore, wicked fast● Tested up to 1,000 nodes against one

PMM Server

Standard and Custom Labels

● Labels, when set, will appear in Query Analytics and can be used to filter● Standard label examples

○ environment○ replication_set○ cluster○ region○ node_model (auto-detected)

● Custom labels are any arbitrary key-value pairpmm-admin add … --environment=production --cluster=MyCluster7 \

--custom-labels="dataCentre=downtown,rack=T3B"

Filtering

● Standard and Custom labels can be used as filter conditions● Additional filters include:

○ Client Host○ Schema○ Client Username○ Database Server

Sorting

● Sort by any column

Add Additional Columns

● Add more columns based on query metadata

● Examples:○ Rows Examined○ Temporary Tables○ Filesort

pmm-agent

● Master daemon on your clients● Runs as root by default● Launches exporters and Query

Analytics agents

Inventory Overview

● View lists of Services, Agents, and Nodes configured

Multiple Collection Intervals

● Collecting metrics aggressively provides the highest level of visibility of events, but at highest storage space cost + disk I/O

● Challenge is to collect highly variable data frequently, or expensive to collect less frequently

● 1s, 5s, 60s are default collection intervals (High, Medium, Low)● Examples:

○ High - Threads_running○ Medium - MySQL Information Schema Thread States○ Low - MySQL Version
