Common ErrorsΒΆ
This list contains some common errors we have encountered over time.
Robusta CLI toolΒΆ
Errors installing the robusta cli config creation tool. Not relevant when using the Web Installation method.
command not found: robusta (CLI not in path)
Determine where the Robusta-cli binary file is located
find / -regex '.*/bin/robusta' 2>/dev/null
Add the path you found (e.g
/opt/homebrew/bin/
) to your PATH. To do so, find your shell config file ( ~/.profile or ~/.bash_profile or ~/.zshrc etc...) and append the following:
export PATH="$PATH:<new-path>"
Reopen the terminal or run:
source <your-shell-config-file>
Alternative Solution
Instead of modifying PATH, run Robusta commands via the python3 binary: python3 -m robusta.cli.main gen-config
SSL certificate errors on Mac OS
This implies a python package with certificates is missing on your system.
To fix it, run /Applications/Python 3.9/Install Certificates.command

Helm installation failsΒΆ
Problems when running helm install
command or installing via GitOps.
unknown field in com.coreos.monitoring.v1.Prometheus.spec, ValidationError(Prometheus.spec)
This indicates potential discrepancies between the version of Prometheus you are trying to use and the version of the CRDs in your cluster.
Follow this guide for upgrading CRDs from an older version.
at least one sink must be defined
Verify sinksConfig
is defined in your Robusta values file, with at least one sink like Slack, Teams or Robusta UI ("robusta_sink"). If it's your first time installing, the fastest solution is to start configue creation from scratch.
Error: UPGRADE FAILED: execution error at (robusta/templates/playbooks-config.yaml:9:7): At least one sink must be defined!
Robusta runner, Prometheus or Holmes failuresΒΆ
robusta-runner pod is in Pending state due to memory issues
If your cluster has 20 Nodes or less, set robusta-runner's memory request to 512MiB in Robusta's Helm values:
runner:
resources:
requests:
memory: 512MiB
limits:
memory: 512MiB
Prometheus' pods are in Pending state due to memory issues
If your cluster has 20 Nodes or less, set Prometheus memory request to 1Gi in Robusta's Helm values:
kube-prometheus-stack:
prometheus:
prometheusSpec:
resources:
requests:
memory: 1Gi
limits:
memory: 1Gi
If using a test cluster like Kind/Colima, re-install Robusta with the isSmallCluster=true
property.
If you're also using Robusta's kube-prometheus-stack, add the lines involving prometheusSpec.
helm install robusta robusta/robusta -f ./generated_values.yaml --set clusterName=<YOUR_CLUSTER_NAME> --set isSmallCluster=true \
--set kube-prometheus-stack.prometheus.prometheusSpec.retentionSize=9GB \
--set kube-prometheus-stack.prometheus.prometheusSpec.storageSpec.volumeClaimTemplate.spec.resources.requests.storage=10Gi \
--set kube-prometheus-stack.prometheus.prometheusSpec.resources.requests.memory=512Mi
robusta-runner isn't working or has exceptions
Start by checking the logs for errors:
kubectl get pods -A | grep robusta-runner # get the name and the namespace of the robusta pod
kubectl logs -n <NAMESPACE> <ROBUSTA-RUNNER-POD-NAME> # get the logs

This error might be due to memory issues. Increase the memory request in Robusta's Helm values:
runner:

requests:
memory: 2048Mi
limits:
memory: 2048Mi
Blocked by firewall / HTTP proxy
If your Kubernetes cluster is behind an HTTP proxy or firewall, follow the instructions in Deploying Behind Proxies to ensure Robusta has the necessary access.
Error in Holmes: binascii.a2b_base64(s, strict_mode=validate)
If the Holmes pod fail to start, with this exception:

It's often because the Robusta UI Token
is pulled from a secret, and Holmes cannot read it.
See Reading the Robusta UI Token from a secret in HolmesGPT to configure Holmes to read the token
Alert Manager is not workingΒΆ
Not getting alert manager alerts
Receiver url has namespace TBD
Tip
If you're using the Robusta UI, you can test alert routing by Simulating an alert.
AlertManager Silences are Disappearing
This happens when AlertManager does not have persistent storage enabled.
When using Robusta's embedded Prometheus Stack, persistent storage is enabled by default.
For other Prometheus distributions set the following Helm value (or it's equivalent):
# this is the setting in in kube-prometheus-stack
# the exact setting will differ for other Prometheus distributions

CRD issuesΒΆ
CustomResourceDefinition.apiextensions.k8s.io "prometheuses.monitoring.coreos.com" is invalid: metadata.annotations: Too long
This is often a CRD issue which can be fixed by enabling server-side apply option as shown below. Check out this blog to learn more.

one or more objects failed to apply... CustomResourceDefinition.apiextensions.k8s.io "prometheusagents.monitoring.coreos.com" is invalid
This indicates potential discrepancies between the version of Prometheus you are trying to use and the version of the CRDs in your cluster.
