SOLVED: Help with Script Data Queries

Post by shull »

I am trying to make my script work and I am having problems. I have followed the docs and I have the script executing as it should. Here are some of the results:

When I execute the script from the command line, it works fine. When I set it up as a device in Cacti, I get this from the Cacti screen.

Please give me direction.


Thanks,

Stephen

There are some syntax errors in your XML, like
<oid_index_parse />
<oid_num_indexes />
Please correct and retry

I just removed those and I still have the same problem. Any other ideas?

Can someone tell me what those errors pertain to or what they mean? If I knew that, I could probably figure it out.

Also, here is the script:

I did not find any obvious error in there. I recommend reading http://docs.cacti.net/node/284. Please try to build a second Script/XML step-by-step as given in this HowTo. This should help you tracking down the error

Thanks,

I did follow that. That is what the script and XML are based on.

If someone could tell me what the error means, I could take it from there. What is Cacti looking for, exactly?

The documentation is good at explaining the "what you do" but there is not any "why you do this" or "here are the reasons this works this way". That, to me, is critical in trying to figure out why something isn't working.

If you have any more knowledge on this, please let me know. How can I see more from the debug logs? Can I log more information? The docs are fine, but they aren't good enough for this issue.

Thanks,

Stephen

Btw, that is correct XML.

That is a short cut for:

Code: Select all

<oid_index_parse></oid_index_parse>
<oid_num_indexes></oid_num_indexes>

OK.

I think I am getting somewhere. Here is what the docs say the output needs to be:

When I run my script fro mthe command line, it outputs data in the form of:

1:2345
2:343433
3:3434



or

1:wewew
2:gdfgdfg
...


This is how the docs said to do it. Is this a problem? That is the only difference I see with the examples in the docs and my script.

I am not sure if this is part of the problem. I am still getting the error when I run a Verbose Query, but it now shows the above information on the Cacti screen.

Please give me some insight.


Thanks,

Stephen

As per http://docs.cacti.net/node/285, calling your script using the parameter index should return a list of indices, one on each line. Please post the result of your script when using this very parameter.
@Tony: Yes, you're quite right. That's the result of spending only a few seconds for quite complex questions. I apologize

Well, this looks fine. Your case will require more time. Hope I find this time this weekend. But documentation of 0.8.7 is waiting for me ...

Thanks for trying to help.

In your opinion, does the output looks right? What should I see in the debugs? What should the verbose query look like?

Thanks,

I've managed to debug it and produce reasonable results. Then I withdraw my debugging changes and it worked as well!?!
Now, I suspect re-indexing issues. To clarify, please perform:
- a re-index by pressing the green circle next to your data query
- following sql command

Code: Select all

SELECT *
FROM `host_snmp_cache`
WHERE `host_id` =2
AND `snmp_query_id` =10
where "2" is the number of the host you've applied the data query to and "10" is the nuber of that very data query. If you place your mouse above the "Verbose Query" link, you will find both numbers as "host_id" and "id", respectively
