For my use case this looks right? (need more clarity on what the
"something" is, in the alert block)
groups:
- name: MemoryAlert
rules:
- record: Memory_Usage_Too_High
expr: 100*(windows_os_physical_memory_free_bytes)/(
windows_cs_physical_memory_bytes)<90
labels:
instance: Server1, Server2
- alert: MemoryUsageTooHigh
expr: |
# Alert based on per-team thresholds.
something #what is this?
> on (instance) group_left
(
Memory_Usage_Too_High
or on (instance)
count by (instance)(something) * 0 + 70 #For all other
instances/server memory usage shouldn't exceed 70%
)
Thank you!
