Step 1: Download agent ``` wget https://github.com/ncabatoff/process-exporter/releases/download/v0.5.0/process-exporter_0.5.0_linux_386.rpm ``` Step 2: Extract the file ``` # rpm -ivh process-exporter_0.5.0_linux_386.rpm ``` Step 3: open all.yaml file and update the process names. ``` process_names: - name: "{{.ExeFull}}" cmdline: - '.+' ``` Step 4: Provision as Linux service ``` #systemctl daemon-reload #systemctl start process-exporter #systemctl status process-exporter ``` Step 5: Update firewalls and ports. Default port is 9256 ``` # firewall-cmd --permanent --add-port=9256/tcp # firewall-cmd --reload ``` ### d) Prometheus exporter for windows machines using WMI. Step 1: Download the msi file ``` https://github.com/martinlindhe/wmi_exporter/releases/download/v0.9.0/wmi_exporter-0.9.0-amd64.msi ``` Step 2: Open powershell and execute the following commands. Please note the commands differ for windows, IIS, MSSQL, etc and are mentioned below as sub-steps Step 2a: For Windows Only ``` msiexec /i ENABLED_COLLECTORS=os,cpu,cs,dns,logical_disk,memory,net,process,service,system,tcp LISTEN_PORT=9182 ``` Step 2b: For IIS only ``` msiexec /i ENABLED_COLLECTORS=os,cpu,cs,dns,logical_disk,memory,net,process,service,system,tcp,iis LISTEN_PORT=9182 ``` Step 2c: For MSSQL ``` msiexec /i ENABLED_COLLECTORS=os,cpu,cs,dns,logical_disk,memory,net,process,service,system,tcp,mssql LISTEN_PORT=9182 ``` Step 2d: For all-in one VM ``` msiexec /i ENABLED_COLLECTORS=os,cpu,cs,dns,logical_disk,memory,net,process,service,system,tcp,iis,mssql LISTEN_PORT=9182 ``` Step 3: You need to enable the respective port in firewall. Note: We cannot run multiple wmi\_exporter in single vm, before executing the command, please check if it needs to be enabled for IIS and MSSql etc. ### e) Prometheus Exporter for Oracle on Linux Please refer the exporter at Github: Step 1: In order to run, you'll need the Oracle Instant Client Basic for your operating system. Only the basic version is required for execution.
Link for Oracle Instant Client Basic: . Select the zip file based on your os type and download the Basic Package (ZIP) Version 18.5.0.0.0 (any zip file in this version) download zip file. At the end of the page, you will have will have steps to how to Installation of ZIP files. Follow those steps carefully.
Step 2: Download the Oracle db exporter agent ``` wget https://github.com/iamseth/oracledb_exporter/releases/download/0.2.2/oracledb_exporter.0.2.2.linux-amd64.tar.gz ``` Step 3: Extract the file ``` # tar -zxf oracledb_exporter.0.2.2.linux-amd64.tar.gz # cd oracledb_exporter.0.2.2.linux-amd64 # nohup ./oracledb_exporter -default.metrics=/home/oracle/oracledb_exporter.0.2.2.linux-amd64/default-metrics.toml -web.listen-address :9161 & ``` Step 4: Enable firewall ports, 9162 is the default port ``` # firewall-cmd --permanent --add-port=9162/tcp # firewall-cmd --reload ``` Step 5: Additional information, set the following paths as an example ``` export ORACLE_HOSTNAME= export ORACLE_UNQNAME=test1 export ORACLE_BASE=/u01/app/oracle export ORACLE_HOME=$ORACLE_BASE/product/12.1.0/dbhome_1 export ORACLE_SID=test1 export PATH=/usr/sbin:$PATH export PATH=$ORACLE_HOME/bin:$PATH export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib:/opt/glibc-2.14/lib:/u01/app/oracle/instantclient_18_5/instantclient_18_5 ```
