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"
