Provides a prometheus exporter for response time metrics.
The following commands are supported (and can/should be configured with BotFather (Edit Commands) for convenience):
status - show the current status of all monitors
chart - <monname> - create a response time chart for monname
members - show active chats (users and groups)
usernames - show usernames (names and their role)
debug - [on|off] - dynamically turn Telegram Bot debugging on/off
restart - restart the bot to pick up DB updates
usernameadd - <username> [reader|admin] - add a username
usernamedelete - <username> - delete a username
silence - <monname> - silence a monitor (keep monitoring, but no alerts)
unsilence - <monname> - unsilence a monitor (revert the silence)
All configuration is done with environment variables. The following envvars are available:
- BOT_TOKEN - the Telegram bot token, should be in the format
<number>:<token> - MAX_ROWS_RESPTIME - The oldest rows in the resptime table are deleted each 10 minutes. This envvar defines how many rows remain per monitor. Default = 1000
- DEBUG - true/false, whether the bot debug should be on or off. Default is false
- PROMETHEUS_EXPORTER_PORT - The port to use for exposing the prometheus exporter (default is 9094). The metric
dhmb_resptime, with labelsnameandstatusis exposed.
