Slackbot stopped sending messages to channel

[RageCPT]

I've recently started working with a new company, they have intergrated Zabbix as a monitoring service that sends notifications to a slack Channel.
The Channel stopped being updated 2 days ago and I have been asked to look into it.

When sending a test via the webhook on the Media Types page I receive:

Slack notification failed : message_limit_exceeded

Any assistance in finding the cause of this problem would be greatly appreciated.

Zabbix 5.4.4.

Hello,

It seems like the Slackbot has stopped sending messages to the channel, and when you tested the Slack integration via the webhook on the Media Types page, you received a "message_limit_exceeded" error. This error suggests that the issue might be related to the number of messages sent to the channel exceeding some limit set by Slack.

Here are some steps you can take to investigate and potentially resolve the issue:

Check Slack API Limits: Slack imposes rate limits on the number of messages that can be sent in a certain timeframe. Ensure that the Zabbix integration is not exceeding these limits. Slack provides detailed information on their API rate limits in their documentation.

Check Zabbix Configuration: Verify the Zabbix configuration for Slack notifications. Check if there have been any recent changes that might have caused the issue. Ensure that the correct Slack webhook URL and credentials are being used for sending notifications.

Check Zabbix Server Logs: Examine the logs on the Zabbix server to see if there are any error messages related to Slack notifications. Logs can often provide valuable insights into what went wrong.

Test with a Smaller Message: Try sending a test notification with a smaller message to see if the issue persists. This will help determine if the problem is specifically related to the message size.

Check Slack Channel Settings: Ensure that the Slack channel itself has not reached its message limit or has any restrictions that prevent messages from being sent.

Verify Webhook Integration: Double-check the Slack webhook integration settings in Zabbix to confirm that they are correct and have not been altered.

I hope the information may helps you.

Thanks with regards,
