Checkmk Werk 14688: Increased metric queue sizes

by Sven Panne

ID: 14688 Title: Increased metric queue sizes Component: cmc Level: 2 Class: Bug fix Version: 2.2.0i1 The internal queues of the CMC for communication with the RRD cache daemon, Carbon connections, and InfluxDB connections has been increased. This can help to reduce the "queue full, didn't push update" messages in the CMC log and the related metric data loss. Note that this will only help when there are load peaks or peaks in the number of produced metrics from time to time. If the monitoring server is not powerful enough to handle the average number of metrics per second in the long run, there will still be data loss.

Checkmk Werk 15010: New notification plugin for Microsoft Teams

by Ronny Bruska

ID: 15010 Title: New notification plugin for Microsoft Teams Component: Notifications Level: 2 Class: New feature Version: 2.2.0i1 This werk enables Checkmk to send notifications about changes in the states of hosts and services to Microsoft Teams. First, you need to setup a webhook to your team or space, see <a href="https://learn.microsoft.com/en-us/microsoftteams/platform/webhooks-and-conn…" target="_blank">here</a> , which will allow Checkmk to post messages. Next, in Checkmk, under "WATO - Notifications", create a new notification rule. Select "Microsoft Teams" as the notification method. Copy the URL of your webhook into the Webhook-URL field. Optionally, if you want sent messages to include hyperlinks to Checkmk, enable the field "URL prefix for links to Checkmk".

Checkmk Werk 14998: Remove long deprecated flexible and plain email notifications

by Ronny Bruska

ID: 14998 Title: Remove long deprecated flexible and plain email notifications Component: Notifications Level: 2 Class: New feature Version: 2.2.0i1 This change only affects you, in case you have set the global setting "Rule based notifications" to "Off" in your installation. Flexible and plain email notifications are deprecated since version 1.5. If you still use flexible or plain email notifications configured within the user profile, this werk will remove this notification option in the usersettings and the GUI. Affected users will be logged to ~/var/log/update.log, e.g.: "Removed notification configuration from user: MY_USER" All listed users will automatically be updated to use the rule based notifications. Effectively, the HTML email notifications will be enabled for them. If you want to use a different notification mechanic, then review the notification rules and update them according to your needs. You can find more about the notification configuration <a href='https://docs.checkmk.com/latest/en/notifications.html'>here</a>. Still existing spool files will be converted to HTML email notifications on update. If a remote site with a version prior 2.2 has flexible or plain email notifications enabled and uses notification forwarding, the notifications will be coverted to HTML email notifications on the recieving site.
