DB2 Monitoring

Prerequisites
  • InfluxDB (the host is the same as Grafana)
  • Separated Linux host
    • Install and running telegraf
    • Install DB2 Client
    • Implement custom scripts
InfluxDB

新增 database

> create database db2_mon with duration 180d
> create user mon with password 'thisispassword'
> grant read on db2_mon to mon

mon 唯讀帳號是給 Grafana 的 datasource 使用。

Telegraf

建立新的設定檔

telegraf --input-filter exec --output-filter influxdb config > /etc/telegraf/telegraf-db2.conf

修改設定檔

  logfile = "/var/log/telegraf/telegraf-db2.log"
  
  
# Configuration for sending metrics to InfluxDB
[[outputs.influxdb]]
  urls = ["http://10.10.2.209:8086"]
  database = "db2_mon"
  timeout = "0s"
  username = "admin"
  password = "Thispassword"

[[inputs.exec]]
    interval = "300s"

    ## Commands array
    #commands = [
    #  "/tmp/test.sh",
    #  "/usr/bin/mycollector --foo=bar",
    #  "/tmp/collect_*.sh"
    #]
    commands = ["sudo -u db2mon sh -c '/home/db2mon/bin/collect_db2.v2.sh -d dcdb -a b_dcdb -u dbuser -p dbpass'"]

    ## Timeout for each command to complete.
    timeout = "5s"

    ## measurement name suffix (for separating different commands)
    #name_suffix = "_mycollector"

    ## Data format to consume.
    ## Each data format has its own unique set of configuration options, read
    ## more about them here:
    ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
    data_format = "influx"

[[inputs.exec]]
    interval = "1h"
    commands = ["sudo -u db2mon sh -c '/home/db2mon/bin/collect_db2x1h.sh -d dcdb -a b_dcdb -u dbuser -p dbpass'"]
    timeout = "5s"
    data_format = "influx"

### CENTDB
[[inputs.exec]]
    interval = "300s"
    commands = ["sudo -u db2mon sh -c '/home/db2mon/bin/collect_db2.v2.sh -d centdb -a b_centdb -u dbuser -p dbpass'"]
    timeout = "5s"
    data_format = "influx"

建立一個新的服務啟動檔

cp /usr/lib/systemd/system/telegraf.service /usr/lib/systemd/system/telegraf-db2.service
