What is the tolerance for read_pod_logs

[Lawouach]

Hello!

I think the read_pod_logs probe doesn't return a boolean so the tolerance would be incorrect. Maybe use a jsonpath or regex instead?

for instance:
https://docs.chaostoolkit.org/reference/tutorials/tolerance/#validate-the-stdoutstderr-of-a-process

Thanks for the help!
I have added something like this
{
"name": "fetch-guamapper-pod-logs",
"type": "probe",
"tolerance": {
"type": "regex",
"pattern": "@timestamp",
"target": "stdout"
},
"provider": {
"func": "read_pod_logs",
"arguments": {
"name": "guamapper",
"last": "30m",
"ns": "core"
},
"type": "python",
"module": "chaosk8s.pod.probes"
}
}

where the logs I should receive from kubectl is similar to -

where I am searching for "timestamp"

the Pod Yaml contains labels -
labels:
app.kubernetes.io/environment: p
app.kubernetes.io/instance: guamapper
app.kubernetes.io/name: guamapper
pod-template-hash: 574f89f4cd

Am I missing something? Or is there a syntax error, I am looking for last 30 minutes logs

It gives an error -
