Zabbix Preprocessing

[BalaC]

Hi,

I'm using my prometheus integration with zabbix. Here I'm trying to monitor the pod status.
My pod `test-postgres-k8sdev-cluster-pooler-repl-6f797d558-n86gs` in `crashloopback`, I fixed it and then it started as different name.
But in check still for pod `test-postgres-k8sdev-cluster-pooler-repl-6f797d558-n86gs` its `0` and I could still see in the `latest data` with greyed out with below error:
```
Preprocessing failed for: {"data":[{"pod":"haproxy-564cf4b9c9-dxmjr","state":"1"},{"pod":"loop-review-postgres-k8sdev-clust...
1. Failed: cannot extract value from json by path "$.data[?(@.pod=='test-postgres-k8sdev-cluster-pooler-repl-6f797d558-n86gs')].state.first()": no data matches the specified path
```

How can I pass preprocessing JSONPath to set to value `1` if the podname itself not found in the current fetched data.

I used this doc for this integration. https://cloud.redhat.com/blog/monito...prometheus-api

thanks

Does the Keep lost resources period not fix that for you (default 30days)

try this: $.data.[?(@.pod=='test-postgres-k8sdev-cluster-pooler-repl-6f797d558-n86gs')].state
Look at the extra . before the [ bracket.

Thanks for the reply. My concern is the pod which restarted will have different name, so offcourse this pod will not be there in the actual output after restart. So how can I handle this or how to ignore this deleted pod? But in latest data still I see all the deleted pod as well which is currently not there.

Then you must work with LLD discovery to detect and auto create the new pod item(s).
And with the macros you have you can also create triggers which uses the correct key values. I'm not known with the prometheus intergration, only tried to help with the jsonpath

LLD discovery detects the new pod items correctly. But how to delete the old pod(item) that is not exist anymore. Becuase it just stay there in the Latest data. Then either we need to manually delete it and close the alert manually as well.
