Cacti monitoring disk io (RHEL)

1. Check whether net-snmp supports Io monitoring.

Snmpwalk-V 1-ip ucd of the cpublic monitoring machine | more

Run the preceding command. If the returned data is similar to the following, the monitoring of diskio is supported. Otherwise, the diskio-module needs to be re-compiled.

1. UCD-DISKIO-MIB: diskioindex.1 = integer: 1

2. UCD-DISKIO-MIB: diskioindex.2 = integer: 2

3. UCD-DISKIO-MIB: diskioindex.3 = integer: 3

2. cacti-devio template:

Original: Cacti_Net-SNMP_DevIO_v3.1.tar.gz

Net-snmp_devio.xml

Net-snmp_devIO-BytesRW_graph_TMPL.xml

Net-snmp_devIO-Data_query.xml

Net-snmp_devIO-LoadAVG_graph_TMPL.xml

Net-snmp_devIO-ReadsWrites_graph_TMPL.xml

Modified: Cacti_Net-SNMP_DevIO_centos5.tar.gz

Modified part: Due to name issues, the Unified Data Template is split and the load part is removed (SNMP does not include this part in version 5, which is included in version 6)

Net-snmp_devio.xml

Cacti_data_query_ucdnet _-_ get_device_io.xml

Cacti_graph_template_ucdnet _-_ device_io _-_ bytes_readwritten.xml

Cacti_graph_template_ucdnet _-_ device_io _-_ readswrites. xml

3. Upload XML:

1. Upload the net-snmp_devio.xml to the var/www/html/cacti/resource/snmp_queries/directory.

2. grant permissions at the same time: chown cacti. cacti net-snmp_devio.xml

Chmod 644 net-snmp_devio.xml

4. Import a template

Use the "importtemplates" in the cacti background to import all *. XML files, and finally the cacti_data_query_ucdnet _-_ get_device_io.xml file. After that, you can see "UCD/net-Get device I/O" in "dataqueries ".

5. Add disk I/O monitoring for the existing "UCD/NET snmphost.

Switch to "devices", click the existing "UCD/net snmp host" host, and check it at the end of the page. In the "add data query" section of "associated dataqueries: "select" UCD/net-Get device I/O "," re-indexmethod: "select" index count changed ", and click" add "to add data queries.

6. Create Io Image Monitoring

Click "create graphs for this host" in the header of the page"
Under Data Query [UCD/net-Get devicei/o] ", select the disk to be monitored and click" CREATE "to create the image.
So far, the cacti monitoring disk Io settings have been completed.
