Hello all, I feel this is really obvious task but I just cant sort it out.We have many Percona master/slave pairs which are monitored using prometheus-mysqld-exporter. I need to display the cpu load factor and other items for the master server within grafana. Has anybody got a grafana expression to isolate the master\_hosts. It is  easy to get any stat for the slave. But how do I get info for the master? ---

Hi, IMHO it’s possible to fetch all slave services in a variable and then ignore such services in formulas. ![](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/1X/ea1685eff049299768ce90163318bc7bd6b6dfca.png "Image: /uploads/percona1/original/1X/ea1685eff049299768ce90163318bc7bd6b6dfca.png") ![](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/1X/c3b1dea14db38dc9b683c1b3aa2b1ae8a39a105d.png "Image: /uploads/percona1/original/1X/c3b1dea14db38dc9b683c1b3aa2b1ae8a39a105d.png")
