alert'd - a simple alerting daemon

data sources

At the moment alert'd supports graphite.

configurable notification channels

Notification channels can be added through configurable shell commands.

"notification_channels": [
  {
    "name": "mailto",
    "#": "The following environment variables are available NAME, SUBJECT, MESSAGE, DATA_SOURCE, QUERY, THRESHOLD, SERIE, and VALUE.",
    "#": "RECIPIENT is configured per subscription",
    "#": "MESSAGE is also piped via stdin",
    "command": "mail -s \"$SUBJECT\" \"$RECIPIENT\""
  },
  {
    "name": "slack",
    "command": "curl -fsS --header 'Content-type: application/json' --data \"{\\\"text\\\": \\\"$MESSAGE\\\"}\" \"$RECIPIENT\""
  }
],

simple message and subject templates

Using shell-like $VAR and ${VAR} string interpolation.

  "#": "The subject and message templates.",
  "#": "All variables except for SUBJECT, MESSAGE, and RECIPIENT are available.",
  "subject_template": "$NAME check failed for $SERIE",
  "message_template": "$SUBJECT: value $VALUE > threshold $THRESHOLD.\n$DATA_SOURCE: $QUERY\n",
