  ...

Show json state of alerts

  $ wavectl show -o json alert
  {
      "additionalInformation": "This alert tracks the used network bandwidth percentage for all the compute-* (compute-master and compute-node) machines. If the cpu utilization exceeds 80%, this alert fires.",
      "condition": "ts(proc.net.percent,server_type=\"compute-*\" and env=\"live\") > 80",
      "displayExpression": "ts(proc.net.percent,server_type=\"compute-*\" and env=\"live\")",
      "id": "1523082347619",
      "minutes": 2,
      "name": "Kubernetes - Node Network Utilization - HIGH (Prod)",
      "resolveAfterMinutes": 2,
      "severity": "WARN",
      "tags": {
          "customerTags": [
              "kubernetes",
              "skynet"
          ]
      },
      "target": "pd: 05fe8ebacf8c44e881ea2f6e44dbf2d2"
  }
  {
      "additionalInformation": "This alert tracks the used cpu percentage for all the compute-* (compute-master and compute-node) machines. If the cpu utilization exceeds 80%, this alert fires.",
  ...

Modify a dashboard's json and write it back to Wavefront

  $> vim ./metadata-dashboard.json    # Modify the json state of a dashboard
  $> wavectl push ./metadata-dashboard.json  dashboard  # Write the new version to Wavefront

  Replaced dashboard(s):
  ID              NAME            DESCRIPTION                                
  metadata-php    Metadata PHP    Monitors for Metadata in the PHP webapp

Example Use Cases

Installation

   pip install wavectl

A note about Performance

wavectl's execution time depends on the number of alerts or dashboards you have in Wavefront. All resource filtering except the --customerTag, -t option is done on the client side. This enables the powerful regular expression matching on your results. But if your organization has thousands of alerts and dashboards, the data size may overwhelm the wavectl execution time.

If your organization has a lot of alerts and dashboards in Wavefront we strongly recommend to use --customerTag option in your commands. The filtering based on customerTag is done on the Wavefront server side. With --customerTags option, wavectl client will only receive data about alerts/dashboards if they are tagged with all of the specified tags. This reduces the data size processed by wavectl and results in faster execution.

Notes

If you could not find what you were looking for please consider contributing. You could also take a look at another CLI implementation for Wavefront. That one is written by Wavefront and mirrors their web api more closely. This wavectl CLI has evolved from our use cases.

wavectl is designed to add automation, command line access to Wavefront data that is human generated. Initial examples are alerts and dashboards. We see those as more permanent, slow changing state in Wavefront. wavectl is not optimized to read, write time series data to Wavefront or any other data that is ingested by Wavefront at real time production workload scale.
