Dynatrace offers a special self-monitoring category of metrics to provide observability into the operation and health of Dynatrace components and features. These metrics are available in every Dynatrace Managed and SaaS environment and can be identified by the dsfm: metric prefix.
For more information, see Self-monitoring metrics.
Following is the list of self-monitoring metrics that can be used to get insights into the operation of an ActiveGate.
Active Gate - Aws - Elements - Bad
Count of elements that were successfully retrieved from AWS, but failed later on (e.g., due to parsing errors). Elements are e.g., number of metrics for metric query, number of instances for instances query etc.
Active Gate - Aws - Elements - Reported
Count of elements that were successfully reported (sent) to the server by ActiveGate. Elements are e.g., number of metrics for metric query, number of instances for instances query etc.
Active Gate - Aws - Elements - Total
Count of all elements retrieved in the given timeframe. Elements are e.g., number of metrics for metric query, number of instances for instances query etc.
Active Gate - Aws - Data Delay
Sum of data delay (difference between expected last timestamp and actual last timestamp) for all entity and metric combinations
Active Gate - Aws - Data Lost
Flag indicating whether we failed to obtain some of the data. 0 - all data obtained, 1 - some data lost.
Active Gate - Aws - Empty Responses
Count of requests whose responses were empty even though we expected some data.
Active Gate - Aws - Missing Permissions
Missing Permissions in AWS monitoring
Active Gate - Aws - Monitored Entities
Number of monitored entities per AWS Credentials
Active Gate - Aws - Query Time
Summed time in milliseconds of all queries in the given timeframe.
Active Gate - Aws - Requests
Count of performed HTTP requests.
Active Gate - Communication - Agent Modules - Connected
Number of OneAgent modules connected.
Active Gate - Communication - Messages - Dropped
Number of messages dropped due to timeouts. Non-zero value indicates data loss.
Active Gate - Communication - Messages - Rejected
Number of messages rejected due to authorization issues. Non-zero value indicates data loss.
Active Gate - Communication - Messages - Resent
Number of messages resent by ActiveGate. Indicates communication issue that may eventually result in dsfm:active_gate.communication.messages.dropped
Active Gate - Communication - Queue - Outgoing - Usage
Number of messages queued. Growing value indicates messages are being received at a faster pace than sent out. Network performance is often a common root cause of this issue.
