MIGRATE TO PMM PROCESS Improve MySQL 6 Months project Production Ready monitoring 3 Members 300+ Instances POC Automated Deployment Acceptance test Customization Deployment 8
MIGRATE TO PMM REASON TO MIGRATE TO PMM WHAT WE HAD Symptom Oriented Focuses on availability & response time Don’t know how application works / Hard to debug Does not expose Application-level metrics 9
MIGRATE TO PMM REASON TO MIGRATE TO PMM WHAT WE WANT Combine Server & Application metrics Detect Both Hardware & Software Potential Problems Capacity Planning / Find under & over resource utilization Database Queries monitoring 10
MIGRATE TO PMM WHAT WE GOT MULTIPLE DATABASES OBSERVABILITY TECHNOLOGIES COMBINE SERVERS & DB METRICS HIGHLY CUSTOMIZABLE DETECT SATURATION / ERRORS NOT CLOUD BASED SPEEDS UP TROUBLESHOOTING & EASY TO SETUP QAN OPEN SOURCE STACK PROMETHEUS GRAFANA 11
MIGRATE TO PMM LIMITATIONS Single Docker Scalabily & Requires an Agent Container Flexibility 12
03 / CUSTOMIZATION 13
PMM CUSTOMIZATION OF HOME DASHBOARD : ALL YOU NEED TO KNOW ON YOUR SCREEN Features : ● MySQL Instance state ● Global SWAP/RAM usage ● QAN enabled instances ● Number of instances/clusters ● MySQL versions ● Disk usage Dashboard id : 10583 14
PMM USE VARIABLES TO GROUP YOUR INSTANCES ● Grouping by database name ● Custom metric 15
PMM DON’T FORGET TO PERSONNALIZE YOUR QUERIES-MYSQLD.YML mysql_custom_metric_get_schema_name: query : "SELECT SCHEMA_NAME,0 AS VALUE FROM information_schema.SCHEMATA;" metrics : - SCHEMA_NAME : usage : "LABEL" description : "The name of the MySQL schema" - VALUE : usage : "GAUGE" description : "Fixed value" valentinmysql (repository : MYSQL_PMM-Custom-YAML) 16
PMM THE COMMUNITY IS NECESSARY Status Dot by btplc 17
PMM GROUP REPLICATION DASHBOARD Features : ● Node state ● Node role ● Automatic cluster enrolment ● MySQL Router server name Dashboard id : 10006 18
