[HELP] Input Field>Special Type Code defined as description

[jtsmartins]

Hi all,

Need your support.

We have a script in the Data Input Method, that was working with the "Input Fields > Special Type Code" defined as description.
This was working correctly until we had a problem in Cacti and needed to reinstall it.

Before the problem we had the Cacti 0.8.8a and now we have the 0.8.8b.

Our devices are defined with:
Description = hostname
Hostname = IP address

The script is define as:
/usr/bin/perl <path_cacti>/scripts/test_script.pl <HOST> <GRAPH>

Where HOST is supposed to be the hostname, that in our case is the description and GRAPH is the graph name.

When the script was working correctly this was created as:
Script: /usr/bin/perl /usr/share/cacti/scripts/test_script.pl TESTHOST1 HTTP_RESPONSE_TIME
RRD: /usr/share/cacti/rra/1179/316270.rrd

Now we have:
Script: /usr/bin/perl /usr/share/cacti/scripts/test_script.pl HTTP_RESPONSE_TIME
RRD: /usr/share/cacti/rra/1179/316271.rrd

As you see the <HOST> input field is not field.

Can anyone help with this? What could be the problem?

Thanks in advance, with best regards,
JTSM

You could edit the include/global_form.php file and add the "description" filed to the list of VALID_HOST_FIELDS variable so it looks like this:

Code: Select all

if (!defined('VALID_HOST_FIELDS')) {
        $string = api_plugin_hook_function('valid_host_fields', '(hostname|description|host_id|snmp_community|snmp_username|snmp_password|snmp_auth_protocol|snmp_priv_passphrase|snmp_priv_protocol|snmp_context|snmp_version|snmp_port|snmp_timeout)');
        define('VALID_HOST_FIELDS', $string);
}

Then do a "Rebuild Poller Cache" from the "System Utilities"

Hi phalek,

Thanks for your reply. Sorry for asking, but do we have any other way of doing this without rebuilding the poller? I'm asking this because if we rebuild the poller this will take a huge time, what will cause a very big impact in our daily work.

Cheers,

Ni,

Not sure. The change actualy only occurred after re-saving the device itself. Seems like it gets updated then only.

You can try applying the change, then go to one of the affected devices and hit the "save" button. Then go to the Utilities menu and check the "View Poller Cache". Search for that device and look at the command displayed.

Ok, so this is only if the node was wrongly created... so, if we change this the new nodes will be created with the description, am I right?

Cheers,

[phalek]

No, the node wasn't wrongly created. The new field simply only get's filled with information when hitting the save button.

Remember, it's a manual code change, so every device before adding this code will not have the "description" tag filled with any information

[jtsmartins]

Yes, sorry... wrong usage of words.

I used node when I was meaning to say graph/data source. We manually created the graph/data source, in other words - manually add the device name, after finding this issue, se we wont have any issues in the poller cache.

I think that your suggestion will only affect new graphs/data sources, so I'm thinking that the poller cache is not needed, have you tried it out?

Thanks, cheers,

Ok, just tested and it works without rebuilding the poller cache!

Many thanks!
