Metrics

once an edge device begins communicating with litmus edge manager, the metrics of your edge device become available in the metrics tab the tab is divided into two sections devicehub lists all devices connected to the edge device; shows their status and the number of tags integration lists integration connectors defined for the edge device; shows their status, rate, and buffer size refer to the following metrics you can refer to on the litmus edge manager user ui's edge devices metrics tab section column description \[1] device hub name the name of the device connected to the edge system tags the number of tags associated with the device success | error rate (msgs/min) the rate of successful and error messages per minute for each device status the current status of the device connection a green dot indicates a device is online a red dot indicates a device is offline \[2] integration name the name of the integration service used by the edge system rate (msgs/min) the rate of messages per minute processed by the integration buffer size the current buffer size of the integration status the current status of the integration a green dot indicates online status a red dot indicates offline status additional metrics you can use additional metrics sources to set up an alert based on metrics collected by litmus edge manager the alert can trigger when a variable reaches a specific value or a set/interval of values only one metrics rule can be created per alert see docid\ ssmqidtpobpv95sc3lkac for more note you can set up alert triggers for different metrics of your edge devices in the triggers section in the alerts module review the docid\ z6i7f1kbzshnsn6fzlise for setting up alert triggers refer to the following table for more information on additional metrics available for alerts template source metrics name description / purpose parameters integration connector disk buffer monitor docid\ wpqo1fe02tmx3askewqu6 connector disk buffer, which is used when the connector’s throughput is insufficient to handle all defined tags coming from edge devices target value in mb alert delay in seconds integration connector online status detect unplanned docid\ wpqo1fe02tmx3askewqu6 connector disconnections alert delay in seconds devicehub devicehub (dh) online status detect unplanned disconnections of devicehub (dh) devices alert delay in seconds devicehub devicehub (dh) device data quality monitor the rate of low quality (i e error) messages a high rate of low quality messages indicate a problem with either the physical device or the device driver target value in msgs/minute alert delay in seconds edge device edge device online status detect unexpected disconnections of edge devices alert delay in seconds edge device edge device license expiration detect when the license of an edge device has expired target value in days alert delay in seconds edge device edge device free disk space monitor the available disk space of an edge device target value in percentage alert delay in seconds edge device edge device memory available monitor the available memory of an edge device target value in percentage alert delay in seconds edge device edge device cpu idle monitor the cpu usage of an edge device target value in percentage alert delay in seconds
