Alert Suppression

Hi Team,

Is there any way to suppress a specific alert like CPU saturation on a particular host?

With anomaly detection setting - Host level you will be able to set problem-creation thresholds or switch them off.

Hi @Yosi_Neuman.

Thanks for the suggestion. Can we do it for a specific timeframe as we do it in Maintenace Window?

Hi @Vikas_g1997

There is no why to do that from anomaly detection perspective.

May be you can utilize for that Host anomaly detection API - PUT configuration

Hi @Yosi_Neuman ,

I've a similar requirement where CPU alerts (alerted through metric event) for a specific host has to be suppressed permanently.. Is there a way to do it? Explored maintenance window option but unable to figure out any option that can handle this..

Regards,

Srikanth

@Yosi_Neuman - Do you think adding a dimension filter like below in the metric event would avert alerting for a specific host?

dt.entity.host.name does not contain (case sensitive) xxxx.domain.com

Hi @ssamraj

You can use ne filter with entity id's

But I would use the positive way and tag all the hosts I want to get alert on and use this tag as a filter for this event metric

Thank you @Yosi_Neuman @.. It's one of the option, I was thinking to go for this morning.

Could you please share the steps and screenshot what you have done to suppress CPU usage for host level?.

In few clicks:

configure the maintenance window as per the intended time and occurrence times.
you have two options to select from as per your requirements
narrow the scope or increase it according to the shown criteria below.

Thanks

hi @Vikas_g1997

you can disable it on host or host group level through anomaly detection settings.

Thanks.

Peter_Youssef — Tue, 17 Sep 2024 08:21:00 GMT

through configuration API, you can control the anomaly detection for host.

create access token with the required scope to action it.

thanks.

For maintenance window through API, it has deprecated from env API v1 and v2

available in settings endpoint with schemaid

Hi Peter

In the maintenance window(in the above screenshot) - How to suppress alert for one host and only CPU saturation and only for time period daily 1.00a.m to 5.00a.m

Re: Alert Suppression

Peter_Youssef — Tue, 17 Sep 2024 09:11:48 GMT

Hi @sundarv1

simply specify the entity ID for example HOST-Abcdefghihjk4545454 and entity tag if there

select the duration to once and allocate the suggested timeframe as per your time zone, below are samples.

Thanks. This will stop all alerts for the CI. How do we stop only CPU Saturation alert alone?.

Hi Samar - Does the above solution worked to suppress CPU alerts only during specific period. if so please share steps.

I still don't see an option to use specific event type in the maintenance window. I've submitted RFE, pls refer below.
