Index Base is .1.3.6.1.2.1.25.2.3.1.1.
create xml file.
on the cacti box , go to <path to cacti>/resource/snmp_queries directory
| root@ubuntu12-04-vm4:~# cd /usr/share/cacti/resource/snmp_queries root@ubuntu12-04-vm4:/usr/share/cacti/resource/snmp_queries# |

on the cacti GUI , go to Data Queries ( GUI -> console -> collection methods -> Data Queries )
click Add and register “hrStorageTable.xml”
go to the device and add “SNMP – hrStoragedTable”
click “Verbose Query”
nnn error.
edit xml ( delete “Index_order” )
| # cat hrStorageTable.xml <interface> <name>Get hrStoragedTable Information</name> <description>Get SNMP based Partition Information out of hrStorageTable</description> <index_order_type>numeric</index_order_type> <oid_index>.1.3.6.1.2.1.25.2.3.1.1</oid_index> <fields> <hrStorageIndex> <name>Index</name> <method>walk</method> <source>value</source> <direction>input</direction> <oid>.1.3.6.1.2.1.25.2.3.1.1</oid> </hrStorageIndex> </fields> </interface> |
Okay.
let’s add storage description
edit xml file
| # cat hrStorageTable.xml <interface> <name>Get hrStoragedTable Information</name> <description>Get SNMP based Partition Information out of hrStorageTable</description> <index_order_type>numeric</index_order_type> <oid_index>.1.3.6.1.2.1.25.2.3.1.1</oid_index> <fields> <hrStorageIndex> <name>Index</name> <method>walk</method> <source>value</source> <direction>input</direction> <oid>.1.3.6.1.2.1.25.2.3.1.1</oid> </hrStorageIndex> <hrStorageType> <name>Type</name> <method>walk</method> <source>value</source> <direction>input</direction> <oid>.1.3.6.1.2.1.25.2.3.1.2</oid> </hrStorageType> <hrStorageDescr> <name>Description</name> <method>walk</method> <source>value</source> <direction>input</direction> <oid>.1.3.6.1.2.1.25.2.3.1.3</oid> </hrStorageDescr> <hrStorageAllocationUnits> <name>Allocation Units (Bytes)</name> <method>walk</method> <source>value</source> <direction>input</direction> <oid>.1.3.6.1.2.1.25.2.3.1.4</oid> </hrStorageAllocationUnits> </fields> </interface> |
go to “create graphs for this host”
edit the xml to get output.
| # cat hrStorageTable.xml <interface> <name>Get hrStoragedTable Information</name> <description>Get SNMP based Partition Information out of hrStorageTable</description> <index_order_type>numeric</index_order_type> <oid_index>.1.3.6.1.2.1.25.2.3.1.1</oid_index> <fields> <hrStorageIndex> <name>Index</name> <method>walk</method> <source>value</source> <direction>input</direction> <oid>.1.3.6.1.2.1.25.2.3.1.1</oid> </hrStorageIndex> <hrStorageDescr> <name>Description</name> <method>walk</method> <source>value</source> <direction>input</direction> <oid>.1.3.6.1.2.1.25.2.3.1.3</oid> </hrStorageDescr> <hrStorageAllocationUnits> <name>Allocation Units (Bytes)</name> <method>walk</method> <source>value</source> <direction>input</direction> <oid>.1.3.6.1.2.1.25.2.3.1.4</oid> </hrStorageAllocationUnits> <hrStorageSize> <name>Total Size (Units)</name> <method>walk</method> <source>value</source> <direction>output</direction> <oid>.1.3.6.1.2.1.25.2.3.1.5</oid> </hrStorageSize> <hrStorageUsed> <name>Used Space (Units)</name> <method>walk</method> <source>value</source> <direction>output</direction> <oid>.1.3.6.1.2.1.25.2.3.1.6</oid> </hrStorageUsed> </fields> </interface> |
define the data template
go to “data template”
click Add
add data source “hrStorageUsed” as well.
click “save”
define the graph template
Templates -> Graph templates
click “create”
click “add”
Data Queries -> SNMP – hrStoragedtable
check “hrStorageSize” and “hrStorageUsed”
create graphs for this host
graph
nnn , it’s difficult for me to define custom templates..
