System and status data
All servers configured to be monitored by the PingDataMetrics server store server and host system data.
Server and machine metrics are retrieved from the cn=monitor
backend of the monitored server.
The Stats Collector plugin is responsible for collecting performance data from the cn=monitor
backend. Data includes server responses, replication activity, local database activity, and host system metrics.
The Stats Collector configuration defines:
-
Data sample and collection intervals
-
The granularity of data collected, such as basic, extended, or verbose
-
The types of host system data collected, such as CPU, disk, and network
-
The type of data aggregation that occurs for LDAP application statistics
For more information, see Tuning data collection.
Processing steps
-
Data samples are taken and stored in time-contiguous blocks on the disk of the monitored server.
-
The PingDataMetrics server collection service polls for new sample blocks.
-
The new sample blocks are queued to disk on the PingDataMetrics server.
-
The PingDataMetrics server import service loads new blocks into the database.
