The time.ParseDuration refused to parse them with the reason that a day
can be shorter or longer than 24 hours. But they are already accepted in
Prometheus range query and a custom parser is included in Prometheus
common package so there's no reason amtool cannot use that.
This will be handy in cases you need to create silence for longer periods,
which are unfortunately common.
This is similar to `promtool check-config` and allows one
to validate the alertmanager configuration (as a git presubmit for example).
`govendor fetch github.com/spf13/{cobra,pflag}` was needed to
have support for `Args`.
Found that we are only defining MarshalJSON for the Regexp type for
references not for the direct object
Also took the time to simplify the json.Unmarshal usage in cli/config.go
Fixes#721
I was using the RunE method of cobra.Command which does things with an
error returned from a function. I doesn't seem possible to keep it from
printing usage every time, so I've make a wrapper to use the other
function.
* Implement alertmanager cli tool 'amtool'
The primary goal of an alertmanager tool is to provide a cli interface
for the prometheus alertmanager.
My vision for this tool has two parts:
- Silence management (query, add, delete)
- Alert management (query, maybe more in future?)
Resolves: #567
