<div dir="ltr">Hi,<div><br></div><div>i had similar problem however I don't think my sollution is suitable for you. One type of my devices returned "normal operation" and "active alarm" strings instead of simple 0/1. I made custom alphabet of 40 characters and changed thde snmp plugin. Now if it finds a string in returned gauge value it takes first 11 characters and converts it to 32 bit integer. In the frontend application I have simple parser to convert it back to string.</div><div><br></div><div>Advantage of this approach is that it lets you use threshold plugin on the returned values or visualize them as a chart.

Subject: [collectd] how to collect string values with snmp plugin<br>

<br>
I would like to have collectd parse text values such as those found in<br>
'system' (sysName, sysContact, sysLocation and so on). While researching it<br>
seems that alphanumerical strings should be of the 'octet' type, however<br>
there doesn't appear to be a suitable DataSet in<br>
/usr/share/collectd/types.db by default.<br>
<br>
I can hardly imagine I'm the first one who wants to do this, but I can't<br>
find anything on the subject online so I might be looking completely wrong<br>
at this subject.<br>
<br>
When using snmpwalk I see the values I want to store, but when I ask<br>
collectd to get these values like so:<br>
<br>
<Data "sysName"><br>
Type "absolute"<br>
Table false<br>
Instance "SNMPv2-MIB"<br>
Values "sysName"<br>
</Data><br>
<br>
I can see in the log file that collectd gets the proper result, but doesn't<br>
know what to do with it.<br>
<br>
[2016-02-29 14:53:10] parse_value: Failed to parse string as absolute:<br>
(null).<br>
[2016-02-29 14:53:10] snmp plugin: csnmp_value_list_to_value: Parsing<br>
string as absolute failed: *hostname1*<br>
[2016-02-29 14:53:10] parse_value: Failed to parse string as absolute:<br>
(null).<br>
[2016-02-29 14:53:10] snmp plugin: csnmp_value_list_to_value: Parsing<br>
string as absolute failed: *hostname2*<br>
<br>
Do I need to define a custom data type for this, or is there something else<br>
I should do to get these results?<br>
<br>
Kind regards,<br>
<br>
Niels<br>
