Alert triggered despite condition not being true

We've set up an alert to fire if disk space usage is greater than 97%. However, yesterday, this alert fired despite the disk space usage being around 31% as can be seen from the chart in the alert. Only a single node was affected.

Can you post your alert query and a screen shot of it? Also, make sure you don't have bad data or a query error. Watch for misplaced *s.

Hi Billrothjr,

Here is my alert query: (ts(ops.infrastructure.df.*.df_complex.used, env=prod-*) / (ts(ops.infrastructure.df.*.df_complex.used, env=prod-*) + ts(ops.infrastructure.df.*.df_complex.free, env=prod-*))) > 0.97 . I have attached the screenshot of the alert firing. Please let me know if you need anything else.
