Monitoring Metrics of Logstash Clusters

Function

This section describes CSS metrics that can be monitored by Cloud Eye as well as their namespaces and dimensions. You can use the management console or APIs provided by Cloud Eye to view the monitoring metrics and alarms generated for CSS.

If the pipeline list in the configuration center of the Logstash cluster does not contain the data migration record of the configuration file, the corresponding monitoring record of the Logstash cluster is empty. Go to Configuration Center to create and start a configuration file for data migration.

Monitoring Metrics

Table 1 describes the monitoring metrics of CSS clusters.
Monitored object: CSS clusters This section describes monitoring metrics of Logstash clusters. For details about the monitoring metrics of Elasticsearch clusters, see Monitoring Metrics of Elasticsearch & OpenSearch Clusters.
Monitoring period (original metric): 1 minute

Accumulated value: The value is accumulated from the time when a node is started. After the node is restarted, the value is reset to zero and accumulated again.
