Grafana¶

Loki¶

By enabling this toolset, HolmesGPT will be able to consult logs from Loki by proxying through a Grafana instance.

Configuration¶

The configuration requires a service account token from your Grafana instance.

holmes:
    toolsets:
        grafana/loki:
            enabled: true
            config:
                api_key: <your grafana API key>
                url: https://grafana-url
                pod_name_search_key: "pod"
                namespace_search_key: "namespace"
                node_name_search_key: "node"

Tweaking search terms

You can optionally tweak the search terms used by the toolset. This is only needed if your Loki logs settings for pod, namespace and node differ from the above defaults.

To do so, set any of the following configuration setting as it is described above:

pod_name_search_key: Loki search key for pods
namespace_search_key: Loki search key for namespaces
node_name_search_key: Loki search key for nodes

Enable this integration

To enable this integration, copy the above example into your Helm values for Robusta (generated_values.yaml).

After making changes, apply them using Helm:

helm upgrade robusta robusta/robusta --values=generated_values.yaml --set clusterName=<YOUR_CLUSTER_NAME>
