That would be an interesting read given I've started supporting cacti in my own time. I'll have to see if I can get my boss to spring for it at work since we use it there... though it may be tricky given the year end

I just got my copy

Congrats

I'm also looking for some Cacti users to review the book. I've been notified by my publisher that there are 10 books available free for distribution with a request to leave a review at Amazon. Please PM or send me an email at cactibook@urban-software.com with some details ( Email, Cacti experience ) so I can forward it.

Anyone who wants to take part in this ?

Well, I bought 2 and trying to get one of them to Rony this weekend. Lot's of new stuff in Cacti 1.x.

Does it explain the various data input and queries methods?

I read the preview of the index but I found no trace of PHP server script for example...I'd really use that

I have this, so I will let you know. Funny thing is, I haven't referred to it for a while as I forgot I had it!

Hi, I didn't go into the script server in specifically, just going through building a Data Query like the interface SNMP one.
It has an example for a script Data Input method.

Scripts Server are a bit more complicated than the two mentioned above, so they didn't quite fit into a "Beginners Guide", although my Book sometimes goes into quite some depth.

The easist method is to copy an existing Data Query and adapt it to your needs.

What kind of Query are you thinking of ?

[jhonnyx]

I have two in mind

1) I am currently creating manually Cisco QoS graphs for our SP CEs and that is somehow OK but I would like to automate it (as everything else in my CACTI servers)

2) I would like to convert a perl script for ASA VPN S2S tunnels to PHP script, both have non-linear indexes and while QoS "maybe" could be adapted to a SNMP Query, the VPN tunnel surely needs a script around it (OIDs changes at each tunnel establishment)

[phalek]

I've attached a PHP Script Server template for Cisco QOS. Not sure if it is working properly, but it should be.
It's caching some SNMP data to the "/data/cacti" directory which should be read/writeable by the Cacti poller and Apache server.

Change the following line in the PHP script if you need it to be somewhere else:

Code: Select all

    // Variables
    $tmp_dir = '/data/cacti/';

It's a bit old and I would change it a bit to be compliant with my new programming standards, but at least it should give you a starting point.

[jhonnyx]

Thank you,

let me give it a try

possibly is not compatible with PHP7

Undefined index means that the array didn't have that index. Undefined variable means somehow you got to code without that variabe being set. Neither of these are 7.2 issues. The foreach, means that it wasn't an array or object passed.

[jhonnyx]

Thanks,

That was just my easy assumption, anyway it doesn't read the indexes, seems that OIDs are correct as I am graphing already the QoS on this router

Code: Select all
