The purpose of this page is to describe the various alert notification integrations LogDNA has to offer.
Alerts send out alert notifications to the specified notification channel(s) whenever a log line with specific content appears in that alert's associated View. A bell icon is also displayed to the right of the View name to indicate that this View has an alert attached to it. While most alerts are for a specific View (known as a view-specific alert), you can also define a preset. A preset is an alert template that you can attach to any number of views.
There are two types of alerts you can set on a view.
- Presence Alerts notify you when there are more than the number of matches of your query within a set time frame.
- Absence Alerts notify you when your logs start showing fewer lines than what is expected. This is useful when you want to be alerted for inactivity in your system. To avoid excessive alerts, absence alerts notifications are paused after 24 hours of not receiving logs and should reset after receiving new logs on a particular view.
You can configure any of the following conditions for an alert:
Time frequency: Specify how often to trigger an alert. Valid values are: 30 seconds, 1 minute, 5 minutes, 15 minutes, 30 minutes, 1 hour, 6 hours, 12 hours, 24 hours. 25 hours
Log lines counter: Specify the number of log lines that match the view's filtering and search criteria. When the number of log lines is reached, an alert is triggered. You can decide whether both conditions are checked or only one. If both conditions are set, an alert is triggered when any of the thresholds is reached.
For example, you can configure an alert that is triggered after 30 seconds, or when a 1000 log lines that match the view's filtering and search criteria are collected.
You can configure multiple alert notification channels. Valid channels are:
