In Percona Monitoring and Management (PMM) 1.13 we have adopted Prometheus 2, and with this comes a dramatic improvement in resource usage, along with performance improvements!
What does it mean for you? This means you can have a significantly larger number of servers and database instances monitored by the same PMM installation. Or you can reduce the instance size you use to monitor your environment and save some money.
Let’s look at some stats!
We can see an approximate 5x and 8x reduction of CPU usage on these two PMM Servers. Depending on the workload, we see CPU usage reductions to range between 3x and 10x.
There is also less disk write bandwidth required:
On this instance, the bandwidth reduction is “just” 1.5x times. …[Read more]
