swap warning

[#1]

Hello Cloudera Support,

We are receiving warnings in Cloudera Manager related to swapping activity on one or more cluster nodes. However, swap has already been disabled across all our hosts, and we've verified that no active swap space is configured.

Despite this, Cloudera Manager continues to raise the warning.

We would appreciate your assistance in clarifying the following:

1. What conditions or metrics trigger this warning?

2. Are there additional configurations or steps we should take to prevent this alert?

Please let us know if any diagnostics or host information is required from our end.

Thank you for your support.

(Swap has been disabled across all nodes via OS configuration.)

Best regards,
Modhi Alrashed

Dear @upadhyayk04 ,

I will raise the threshold to be as what you recommended, but the host threshold already 200 ( warning).

Can I change the Process Swap Memory Threshold? to fix my issue ?

Yes, @Malrashed, that should help as well. Mainly we are bypassing the warning by increasing the threshold
