Custom parameters to a script server query

[jsemczyk]

Hi,

Any of you knows a way to give custom parameters to a query script, executed through the PHP script server, from a DataTemplate or DataQuery ?

What I mean is, I created a new data input method with some custom input fields, those fields gets created for each datasources and I wish I could get them from my script.

I tried with the xml tag <arg_prepend> inside my XML dataquery definition but it did not work. It seems I can only fetch variables from the host.

Regards,
Jon.

<arg_prepend> is the only one I can think about. But what kind of parm do you want to pass to the script? Would the script be able to fetch the parms instead?

Yes, for a regular script you can provide additional input variables, but for a Data Query you currently can not. I've needed this a few times myself and sadly don't have time at the moment to fix it.

However, there is hope. Please goto http://bugs.cacti.net and request that a feature be added to allow additional input parameters to a Data Query. No promises, but we will have the request.

Hi,
I'm actually trying to pass some args from my a query I have to a get call. I can't seem to do it using arg_prepend.
I want to have the arg_prepend pass |query_ifindex| |query_ifvpi| |query_ifvci|
Anyway to pass non-host args yet? The most recent post I can find on this is this one from 2002.

For now I'm handling this as a sql request to the host_snmp_cache table that pulls the info I want to pass to my script...but I would prefer to handle this in the xml.

So this is a Script Server Data Query? At least, all |host_*| parameters should be resolved as they are static with regard to running a script.
ifIndex should be passed by the get request, then. But if you have "multiple indexes" like "index, vpi, vci", things get worse.
We do support "multiple indexes" with SNMP Data Queries as long as they can be handles as a "single string", e.g. "OID1.OID2.OID3". In this case, we use the whole string as the index.
This may be extended to Script (Server) Data Queries. but in this case again we would not use arg_prepend in the suggested way.

Yes, It's a script server data query.
The problem is that my devices only have a high level PVC traffic mib that tells me in/out bytes, etc, but doesn't tell give me an index of ifindex/vpi/vci I need to properly call it in snmp.
the oid is like this: oid.ifindex.vpi.vci
The ifindex vpi and vci change every query.
All of the |host* queries work, but I was hoping to append the get with the ifindex.vpi.vci so the script server can append that to the oid when doing the cacti_snmp_get.
My solution with pulling the data from the sql server is currently working, but if my snmp_query_index changes I'd have to update that in the script.

How do you detemine the current "ifIndex.vpi.vci", then?
Is it ok to post the script to understand better?

I'll post it in the morning a long with the stuff for the other post.
Thanks!

Here is the script and script server xml.

There are some new upcoming features; find them here: http://docs.cacti.net/manual:088:3a_adv ... xml_syntax
Does this help?

I found this trick, which doesn't require modifying any cacti code and is a simple solution http://forums.cacti.net/viewtopic.php?f=6&t=55704
