Monitoring metrics can be divided into two categories： + +1. **Process monitoring**: mainly displays some monitoring values of the Doris process itself . +2. **Node monitoring**: mainly displays the monitoring of the node machine itself where the Doris process is located, such as CPU , memory, IO , network , etc. + +You can obtain the current monitoring by accessing the http port of the FE or BE node . like : + +``` +curl http://fe_host:http_port/metrics +curl http://be_host:webserver_port/metrics +``` + +Monitoring metrics are generated in a Prometheus compatible format, for eg: + +``` +doris_fe_cache_added{type="partition"} 0 +doris_fe_cache_added{type="sql"} 0 +doris_fe_cache_hit{type="partition"} 0 +doris_fe_cache_hit{type="sql"} 0 +doris_fe_connection_total 2 +``` + +Monitoring metrics in Json format can be fetched using `type` parameter in rest interface, for eg： + +``` +curl http://fe_host:http_port/metrics?type=json +curl http://be_host:webserver_port/metrics?type=json +``` + +## Monitoring levels and best practices + +**The last column in the table marks the importance level of the monitoring items. P0 means the most important, the larger the value , the lower the importance.** + +The vast majority of monitoring metric types are Counter . That is the cumulative value. You can obtain effective information by collecting monitoring values at intervals (such as every 15 seconds) and calculating the slope per unit time . + +The query error rate can be obtained by calculating the slope of `doris_fe_query_err`, presented as (error per second). + +> 欢迎完善此表格以提供更全面有效的监控指标。 Review Comment: This sentence is missing translation. -- This is an automated message from the Apache Git Service.
