OID REGEX

[raX]

Since a few of you asked above, the two regular expression match functions only work with POSIX regular expressions, not Perl-based ones. If you look in the code, the exact function that is used to match the string is ereg_replace().

I wish I would have realized this before, but all of the options for the "source" item in the XML file only apply to input fields. That is, Cacti uses this information when running the data query, which subsequently affects the data that ends up in the data query cache. What you are left with is a single SNMP OID for each item that is passed directly onto the poller. All the poller sees is the OID at this point, so it only returns the literal value and moves on.

With that in mind, being able to parse output in the poller would be a great feature. As is the case here, it would mainly be useful when dealing with brain dead SNMP implementations since there is little that you can do to affect their output. Feel free to add a bug to bugs.cacti.net if you would like to see this added at some point.

As for now, your best bet is to create a script query which handles all of the parsing for you. It might be a bit more work than an SNMP query, but it would definitely return the results that you are looking for.

WAHOO! Not crazy!

I will bite the bullet for now. But I will put it in as a bug report.

Thanks everyone for the help.

As long as you are running cmd.php, I will provide a fix, but only after we release 0.8.6d. I need some quality time with Cactid. So it will take longer.

i am still using cmd.php.

I was actualy just debating trying it on my own... I'll see what I can do to night, and submit it tomrrow if I am just not getting it.

[TheWitness]

Please try this lib\functions.php with your build and see if it makes the problem go away.

almost... still returned a "partial"

obviously i need to work on my regex for some of them

[TheWitness]

Please post a debug of the same information and then I am concerned about the following:

Please explain the "Bay x:"

For a blade center, you have power domains, a power domain is made up of (curently) 2 power supplies. So the "bay" is the "slot/bay" the power supply is in.


That would be a nice to have, sonce the "bay" can have different sized PSUs installed. Currently I have 1400 Watt PSUs. It would be nice to have to base the graph scall off of. Inother words I dont NEED it but. it would be nice. Obviosuly I am more concerned with the usage. I am turning on a hight debug, will post it in a min

The following is the regex that I use for power domain 1. It does worl via the input method.


<bcblademmINdomain1max>
<name>Power Domain 1 Unit Max Watts</name>
<method>walk</method>
<source>VALUE/REGEXP:Bay [0-9]: ([0-9]{1,4})W$</source>
<direction>input</direction>
<oid>.1.3.6.1.4.1.2.3.51.2.2.10.1.1.1.4</oid>
</bcblademmINdomain1max>

Ok,

I am currently only trimming the trailing non-numeric data. Not data at the front of the string. Therefore, can you make the output not contain the prefix information? I will have another version quite soon.

Still getting a "nan" and no graphs... debug isnt reporting anything out of the ordinary...

I wonder if it would be better to take the ereg_replace code from data_query.php and put that in to the cmd.php

I did remove the domain max queries from the data source, so that shouldn't interfear

I'm carving off 1 too many characters. I have another to give. Please try this one. Sorry for the repetition on this.

Belive me I am not irked at all! I am just glad to have it as close as it is now.
