Steps to get it up and running

  • Create a Data Bag named grack
  • Generate a Grafana API Key
  • Store the key in an encrypted Data Bag Item name grafana in the grack Data Bag with the key api_key.
  • Example: { "id": "grafana", "api_key": "abc123oibTdsYWRTMWtMUnFWR2pGRlpjenRUMWRCMndERmZIV3YiLCJuIjoicmVhZG9ubHkiLCJpZCI6MX0=" }
  • Generate a Slack API Token
  • Store store the token in an encrypted Data Bag Item named slack in the grack Data Bag with the key api_token.
  • Example: { "id": "slack", "api_token": "xoxb-abc12371906-o2HBliCwGgG3R4GS6TPcGzYk" }
  • Set the following attributes
    • node['grack']['graphs']['name_of_graph']['dashboard']['name']: Grafana dashboard name
    • The name of the Grafana dashboard housing the graph you want to send to Slack. It can be found via the Grafana URL for the dashboard itself.
    • Example: https://foobar.com/d/abcdefghi/**mysql**/...
    • node['grack']['graphs']['name_of_graph']['dashboard']['id']: Grafana dashboard id
    • The value immediately preceding the name of the dashboard in your Grafana url.
    • Example: https://foobar.com/d/**abcdefghi**/...
    • node['grack']['graphs']['name_of_graph']['dashboard']['org_id']: Grafana org ID
    • The id of your Grafana organization. It can be found via the Grafana URL for the dashboard itself.
    • Example: https://foobar.com/d/abcdefghi/mysql?panelId=20&**orgId=1**...
    • node['grack']['grafana']['name_of_graph']['dashboard']['variables']: Any Grafana variables the graph depends on
    • IF you're using variables they can be found in the dashboards URL
    • Example: https://foobar.com/d/abcdefghi/mysql?panelId=20&orgId=1&**var-datasource=telegraf&var-region=ireland&var-environment=production**...
    • node['grack']['graphs']['name_of_graph']['hour']: Hour to send the graph. Default is 0
    • node['grack']['graphs']['name_of_graph']['minute']: Minute to send the graph. Default is 30
    • node['grack']['graphs']['name_of_graph']['panel_id']: Grafana graph panel ID
    • The panel ID of the graph itself. Click on the title of the graph, click on share and it will be listed as the panelId in the URL.
    • Example: https://foobar.com/d/abcdefghi/mysql?**panelId=20**...
    • node['grack']['graphs']['name_of_graph']['past_hours']: Number of hours, in the past, to graph. Default is 24
    • node['grack']['graphs']['name_of_graph']['slack_channel']: Slack channel to send graph to
    • node['grack']['graphs']['name_of_graph']['sleep_time']: Amount of seconds to sleep before generating the graph. This is helpful if you're sending a number of graphs during the same minute and would like them sent in the same order each time.
    • node['grack']['grafana']['host']: The fqdn of the Grafana server. Default is localhost
    • Example: "grack" => { "graphs" => { "ireland_production_cpu" => { "dashboard" => { "name" => "mysql, "id" => 'abcdefghi', "org_id" => 1 }, "hour" => 12, "minute" => 0, "panel_id" => 4, "past_hours" => 12, "slack_channel" => "ireland_production_status" } }, "grafana" => { "host" => "foo.bar" },

Setting defaults

You can set graph_defaults to simplify your config: - Example: "grack" => { "graph_defaults" => { "dashboard" => { "name" => "mysql", "id" => "abcdefghi', "org_id" => 1, "variables" => { "datasource" => "telegraf", "environment" => "production" }, "hour" => 12, "minute" => 0, "slack_channel" => "ireland_production_status" }, "graphs" => { "ireland_mysql_connections" => { "panel_id" => 5, "sleep_time" => 2 }, "ireland_mysql_cpu" => { "panel_id" => 4 }, "ireland_mysql_cpu_for_the_past_7_days" => { "hour" => 8, "panel_id" => 4, "past_hours" => 168 } }, "grafana" => { "host" => "foo.bar" },

Removing cron jobs

To remove an existing cron job, set the graph's delete key to true: - node['grack']['graphs'][''name_of_graph'']['delete']: true - Example: ` "grack" => { "graphs" => { "ireland_mysql_connections" => { "delete" => true }
