Hi all,

I'm in need to get 4 values from this type of hw via snmp query.

The data that I need to collect is (integer*10):

channel 1: .1.3.6.1.4.1.22626.1.5.2.1.3.0
channel 2: .1.3.6.1.4.1.22626.1.5.2.2.3.0
channel 3: .1.3.6.1.4.1.22626.1.5.2.3.3.0
channel 4: .1.3.6.1.4.1.22626.1.5.2.4.3.0

but I have no idea how to create a "query template" without referincing to an snmp table

Any ideas?
Ciao e grazie! Luciano

>> but I have no idea how to create a "query template" without referincing to an snmp table

Please explain in detail about that..

What I mean is that if I create a data query in this way:

Code: Select all

<query>
   <name>Get Channel 1</name>
   <description>Query Sonda - CH 1</description>
   <oid_index>.1.3.6.1.4.1.22626.1.5.2.1.3</oid_index>
   <index_order_type>numeric</index_order_type>
   <index_title_format>TEST 1</index_title_format>

   <fields>
      <ifIndex>
         <name>Index</name>
         <method>get</method>
         <source>value</source>
         <direction>output</direction>
         <oid>.1.3.6.1.4.1.22626.1.5.2.1.3.0</oid>
      </ifIndex>
   </fields>
</query>

I get this:

+ Running data query [11].
+ Found type = '3' [snmp query].
+ Found data query XML file at '/var/www/html/resource/snmp_queries/sonda_ced_1.xml'
+ XML file parsed ok.
+ Executing SNMP walk for list of indexes @ '.1.3.6.1.4.1.22626.1.5.2.1.3'
+ Index found at OID: '1.3.6.1.4.1.22626.1.5.2.1.3.0' value: '266'
+ Found data query XML file at '/var/www/html/resource/snmp_queries/sonda_ced_1.xml'
+ Found data query XML file at '/var/www/html/resource/snmp_queries/sonda_ced_1.xml'
+ Found data query XML file at '/var/www/html/resource/snmp_queries/sonda_ced_1.xml'

so I get the value (which should be 26.6 degree) but when I try to create a graph I get "This data query returned 0 rows" ... O_o

Ciao e grazie!

Well, (just guessing)

1) There is no field which has "<direction>input</direction>".
2) If your device has single (not multiple) SNMP OID for that value, no need to create SNMP data query. Use "SNMP - Generic OID Template" graph template.

Additionally, if you want to draw the value as 26.6 (not 266), create CDEF like "cdef=a,10,/" and use it in graph template.

Ciao,

I used the Generic template, inserting the OID .1.3.6.1.4.1.22626.1.5.2.1.3.0 but no data is returned ... while, if I used the DataQuery:

Code: Select all

<query>
   <name>Get Channel 1</name>
   <description>Query Sonda - CH 1</description>
   <oid_index>.1.3.6.1.4.1.22626.1.5.2.1.3</oid_index>
   <index_order_type>numeric</index_order_type>
   <index_title_format>TEST 1</index_title_format>

   <fields>
      <ifIndex>
         <name>Index</name>
         <method>get</method>
         <source>value</source>
         <direction>input</direction>
         <oid>.1.3.6.1.4.1.22626.1.5.2.1.3.0</oid>
      </ifIndex>
   </fields>
</query>

get this:

Code: Select all

+ Running data query [11].
+ Found type = '3' [snmp query].
+ Found data query XML file at '/var/www/html/resource/snmp_queries/sonda_ced_1.xml'
+ XML file parsed ok.
+ Executing SNMP walk for list of indexes @ '.1.3.6.1.4.1.22626.1.5.2.1.3'
+ Index found at OID: '1.3.6.1.4.1.22626.1.5.2.1.3.0' value: '251'
+ Located input field 'ifIndex' [get]
+ Executing SNMP get for data @ '.1.3.6.1.4.1.22626.1.5.2.1.3.0.251' [value='']
+ Found data query XML file at '/var/www/html/resource/snmp_queries/sonda_ced_1.xml'
+ Found data query XML file at '/var/www/html/resource/snmp_queries/sonda_ced_1.xml'
+ Found data query XML file at '/var/www/html/resource/snmp_queries/sonda_ced_1.xml'

The value is get (251) but is not used as a value but append to the snmp OID .... arghhhh!!!

Ciao ciao!

"<direction>input</direction>" is for the selection table when creating graph. (e.g. index, description, etc.)
"<direction>output</direction>" is for drawing graph. (numeric value only)
Both fields are needed.
- SNMP Data Queries - Cacti Docs

(NOTICE: Output field will not be shown in verbose query)

Anyway, try this query for test:

Code: Select all

<query>
   <name>Get Channel Temperature</name>
   <description>Query Sonda - CH x</description>
   <oid_index>.1.3.6.1.4.1.22626.1.5.2</oid_index>
   <oid_index_parse>OID/REGEXP:.*\.([0-9]+)\.3\.0$</oid_index_parse>

   <fields>
      <ChIndex>
         <name>Index</name>
         <source>index</source>
         <direction>input</direction>
      </ChIndex>
      <ChTemp>
         <name>CH Temperature</name>
         <method>walk</method>
         <source>value</source>
         <direction>ouput</direction>
         <oid>.1.3.6.1.4.1.22626.1.5.2</oid>
         <oid_suffix>3.0</oid_suffix>
      </ChTemp>
   </fields>
</query>

I assume the following result when you perform snmpwalk to the device.

% snmpwalk -v1 -c <community> <device> .1.3.6.1.4.1.22626.1.5.2
.1.3.6.1.4.1.22626.1.5.2.1.3.0 = xxx
.1.3.6.1.4.1.22626.1.5.2.2.3.0 = xxx
.1.3.6.1.4.1.22626.1.5.2.3.3.0 = xxx
.1.3.6.1.4.1.22626.1.5.2.4.3.0 = xxx
