Config File:
|
|
The alertmanager tool will read a config file in YAML format from one of two
|
|
default config locations: $HOME/.config/amtool/config.yml or
|
|
/etc/amtool/config.yml
|
|
|
|
All flags can be given in the config file, but the following are the suited for
|
|
static configuration:
|
|
|
|
alertmanager.url
|
|
Set a default alertmanager url for each request
|
|
|
|
author
|
|
Set a default author value for new silences. If this argument is not
|
|
specified then the username will be used
|
|
|
|
require-comment
|
|
Bool, whether to require a comment on silence creation. Defaults to true
|
|
|
|
output
|
|
Set a default output type. Options are (simple, extended, json)
|
|
|
|
date.format
|
|
Sets the output format for dates. Defaults to "2006-01-02 15:04:05 MST"
