1. add some metrics for cpu monitor;
2. add metrics for process state monitor;
3. add metrics for memory monitor;
It is convenient for us to use grafana to filter through different conditions.
After the added, we can find the cpu metrics like this：
doris_be_cpu{device="cpu1",mode="guest_nice"} 0
doris_be_cpu{device="cpu1",mode="guest"} 0
doris_be_cpu{device="cpu1",mode="steal"} 0
doris_be_cpu{device="cpu1",mode="soft_irq"} 107168
doris_be_cpu{device="cpu1",mode="irq"} 0
doris_be_cpu{device="cpu1",mode="iowait"} 3726931
doris_be_cpu{device="cpu1",mode="idle"} 2358039214
doris_be_cpu{device="cpu1",mode="system"} 58699464
doris_be_cpu{device="cpu1",mode="nice"} 1700438
doris_be_cpu{device="cpu1",mode="user"} 54974091
we can find the memory metrics as follow：
doris_be_memory_pswpin 167785
doris_be_memory_pswpout 203724
doris_be_memory_pgpgin 22308762092
doris_be_memory_pgpgout 152101956232
we also can find the process metrics as follow:
doris_be_proc{mode="interrupt"} 421721020416
doris_be_proc{mode="ctxt_switch"} 2806640907317
doris_be_proc{mode="procs_running"} 8
doris_be_proc{mode="procs_blocked"} 3
Apache Doris (incubating)
Doris is an MPP-based interactive SQL data warehousing for reporting and analysis. Its original name was Palo, developed in Baidu. After donated to Apache Software Foundation, it was renamed Doris.
-
Doris provides high concurrent low latency point query performance, as well as high throughput queries of ad-hoc analysis.
-
Doris provides batch data loading and real-time mini-batch data loading.
-
Doris provides high availability, reliability, fault tolerance, and scalability.
The main advantages of Doris are the simplicity (of developing, deploying and using) and meeting many data serving requirements in a single system. For details, refer to Overview.
