Doesn't work with large alerts count

[bykvaadm]

in test prometheus i had about 160 alarts with same type "instance xxx is down".

• when sending commnd /alerts to bot in tcpdump i see that it goes to alermanager api and gets all alerts, but in telegrab bot replies "failed to list alerts... context canceled"
• when receiving webhook, bot prints 160 times template text, w/o jobs, labels etc
• when i commented 90% of failing jobs, bot began to work normally

There's a limit to how many characters can be sent in a single Telegram message.
Starting from v0.4.0 onwards the bot automatically truncates messages that are too long.
Which version are you running?

Same issue here. Same error when loads of alert are firing.
Running latest version.
According to logs, everything is fine.

Same issue for me. there must be problem in fetching alerts from url when the number of alerts is large

I have similar situation. When i keep send /alerts command for a couple of times, sometimes it will show below. anything update for this?

failed to list alerts... Get http://192.168.164.56:9093/api/v1/alerts: dial tcp 192.168.164.56:9093: connect: connection refused
