The tech team uses Monyog for monitoring their MySQL servers. Recently, the CloudMagic team reported that Monyog helped them quickly identify the reason behind an issue.
Here's what happened:
Amazon Web Services had promoted the standby instance as the primary one. When AWS RDS does a failover connections to the server generally fails for a couple of minutes. This is what happened for one of their RDS servers and PagerDuty alerted them. Just when they started to debug, a Monyog alert cut short debugging time to under a minute. Below is the alert mail sent by Monyog, at the same time when PagerDuty alert went off.
The specific configuration that generated the alert:
Below is the screenshot from Monyog’s configuration page where you can enable this alert:
What would have happened without Monyog's alerting capabilities?
The team would have spent more time shuffling through various dashboards and monitors to find the particular issue and take appropriate actions. Monitoring your MySQL servers requires the ability to identify critical events amongst others.
Happy Monitoring!
