Collect and monitor general performance metrics for DORIS database FE. Supports DORIS 2.0.0.
Protocol: HTTP
Pre-monitoring operations
Check the fe/conf/fe.conf file to obtain the value of the http_port configuration item, which is used for monitoring.
Configuration Parameters
Parameter Name
Parameter Description
Monitor Host
The monitored target's IPV4, IPV6, or domain name. Note: Without the protocol header (e.g., https://, http://)
Task Name
A unique name identifying this monitoring task
Port
The port provided by the database to the outside, default is 8030 ,get the value of thehttp_port configuration item
Query Timeout
The timeout for the connection to not respond, in milliseconds, default is 3000 milliseconds
Database Name
Optional database instance name
Collection Interval
The interval between periodic data collections for monitoring, in seconds, with a minimum interval of 30 seconds
Probe Required
Whether to probe and check the availability of monitoring before adding new monitoring, continue with the addition or modification operation only if the probe is successful
Description
Additional notes and descriptions for this monitoring task
Collection Indicators
Metric Set: doris_fe_connection_total
Metric Name
Metric Unit
Metric help description
value
None
The current number of MySQL port connections on FE
Metric Set: doris_fe_edit_log_clean
Should not fail; if it does, manual intervention is required.
Metric Name
Metric Unit
Metric help description
success
None
The number of successful cleanups of historical metadata logs
failed
None
The number of failed cleanups of historical metadata logs
Metric Set: doris_fe_edit_log
Metric Name
Metric Unit
Metric help description
write
None
The count of metadata log write operations
read
None
The count of metadata log read operations
current
None
The current number of metadata logs
accumulated_bytes
Bytes
The cumulative value of metadata log writes
current_bytes
Bytes
The current value of metadata logs
Metric Set: doris_fe_image_clean
Should not fail; if it does, manual intervention is required.
Metric Name
Metric Unit
Metric help description
success
None
The number of successful cleanups of historical metadata image files
failed
None
The number of failed cleanups of historical metadata image files
Metric Set: doris_fe_image_write
Should not fail; if it does, manual intervention is required.
Metric Name
Metric Unit
Metric help description
success
None
The number of successful generations of metadata image files
failed
None
The number of failed generations of metadata image files
Metric Set: doris_fe_query_err
Metric Name
Metric Unit
Metric help description
value
None
The cumulative value of erroneous queries
Metric Set: doris_fe_max_journal_id
Metric Name
Metric Unit
Metric help description
value
None
The current maximum metadata log ID on the FE node. If it is a Master FE, it is the maximum ID currently written; if it is a non-Master FE, it represents the maximum metadata log ID currently being replayed. Used to observe if there is a large gap between the IDs of multiple FEs. A large gap indicates issues with metadata synchronization
Metric Set: doris_fe_max_tablet_compaction_score
Metric Name
Metric Unit
Metric help description
value
None
The largest compaction score value among all BE nodes. This value can observe the current cluster's maximum compaction score to judge if it is too high. If too high, there may be delays in queries or writes
Metric Set: doris_fe_qps
Metric Name
Metric Unit
Metric help description
value
None
The number of queries per second on the current FE (only counts query requests)
Metric Set: doris_fe_query_err_rate
Metric Name
Metric Unit
Metric help description
value
None
The number of erroneous queries per second
Metric Set: doris_fe_report_queue_size
Metric Name
Metric Unit
Metric help description
value
None
The length of the queue for various regular reporting tasks on the BE side at the FE end. This value reflects the degree of blocking of reporting tasks on the Master FE node. A larger value indicates insufficient processing capacity on the FE
Metric Set: doris_fe_rps
Metric Name
Metric Unit
Metric help description
value
None
The number of requests per second on the current FE (includes queries and other types of statements)
Metric Set: doris_fe_scheduled_tablet_num
Metric Name
Metric Unit
Metric help description
value
None
The number of tablets currently being scheduled by the Master FE node. This includes tablets that are being repaired and tablets that are being balanced. This value can reflect the number of tablets currently migrating in the cluster. If there is a value for a long time, it indicates that the cluster is unstable
Metric Set: doris_fe_txn_status
Can observe the number of import transactions in various states to determine if there is a backlog.
