SQL Logging

Hi Experts,

I have to create a template with some indicators for our SQL AG Cluster 2014.
We want to measure these indicators and check performance before and after a deployment.

Can you help me to find very important KPI´s to put into my template ?

Now I monitoring these:
Cache Hit Ratio
Page Life Expactency
CPU Utilization
Disk IO

What else is important to check ?

The first tests showed me a PageLifeExpactency from 3000.
Is it now good to have a high value or bad because the data stays too long in the buffer ?
Deepak ChauhanSQL Server DBACommented:
PLE value 3000 is a great value from performance point of view and higher value leading to higher performance. This value is in seconds which means 50 minutes indicate no memory pressure on the server and buffer cache hit ratio would be 99.9 % if you check there. Minimum value of this counter is 300 seconds in a busy system and should not be reduce else need to take a look into memory.

Since this is AG cluster so you can take a look through these counters as well for AG.
