Getting value of text parameter

If I have a text parameter that contains text only can I pull the text of that parameter some how? I have tried to get it using the get("/".applicationclass."/"instance."/".parameter."/value); command with out any luck. Using that command I can get values on graphs but that's about it. Any ideas?

Thanks

Robbie,

Nothing wrong with your example, the same method should work for a text parameter !
So there must be something else wrong ...

Can you give us a glimp of the code that populates the text parameter and the one that get's the value?

Hey Bert. Thanks for the reply.

It's pretty basic, the only exception may be I'm trying to pull the data in the text parameter from event catalog 11. I can get the value of a graph parameter without issue. Here is the code:

populate
set("../LOGAlarms/value", errdisp, unique(matchedline) ); #errodisp is a title and matchedline is text pulled from a log file.

pull
almtxt = get("/".applicationclass."/".instance."/LogAlarms/value");
What I'm trying to do is pass the text from the LOGAlarms parameter through SNMP to a SNMP management system but I can't even get the text to print in the SOW. I agree with you IT SHOULD WORK. The text is present in the LOGAlarms parameter. Weird!

Thanks for your help,
Rob

Whoa...hold it Unless the unique(matchedline) returns a timestamp....and a recent one you will have problems here. The third argument of set() should be a timestamp in seconds past the epoch format. If your unique(matchedline) is textual it will evalute to 0 numerically...which would represent the epoch....Dec 1970....which is likely way outside your retention period for history even...and definately not the most recent value of this parameter.

Perhaps you meant

<br/>set&#40;&quot;../LOGAlarms/value&quot;, errdisp . &quot;\n&quot; . unique&#40;matchedline&#41; &#41;; <br/>

Msharpe,

Aren't you talking about the batch_set() function instead of the set() function ?
Or is this un undocumented feature of the set() function, because I can't find any reference to a third parameter for the set() function (3.4 and 3.5 manual)?

Greetz,
Bert

The timestamp works on set() too. Thought we had that doc'ed now? Guess not. Will address that.

Indeed, this is undocumented in the manual, but already documented in the devcon forum since 2000 ...

What's the difference with Batch_set() then ...

I could do a search offcourse, because I did see a topic about this function, but since we're on the topic anyway ;-)

set() :  sets a single value, with a single call on a single namespace variable.

batch_set() : allows you to combine multiple set()'s in a single PSL instruction, wasting less resources.

This is just to prevent
set()
set()
set()
...
set()

Nothing more !

Hey guys, going back to msharpe's first comment, yes the lines are time stamped. The problem isn't that the lines of text aren't in the parameter or they aren't all making it. The problem is I can't pull anything from the text parameter. Any suggestions?

Strange ...

Just to help us move forward on this, could you remove the timestamp from the set instruction (for now) ?

Also after you set the paramter - looks like you are doing it from another parameter - just do the following :

<br/>set&#40;&quot;../LOGAlarms/value&quot;, errdisp &#41;; <br/>parampath = &quot;/&quot;.get&#40;&quot;../../name&quot;&#41;.&quot;/&quot;.get&#40;&quot;../sid&quot;&#41;.&quot;/LOGAlarms/value&quot;;<br/>print&#40;&quot;TESTING print&#40;get&#40;&quot;.parampath.&quot;&#41;&#41;; = &quot;.get&#40;parampath&#41;.&quot;\n&quot;&#41;;<br/>



Now see what get's printed in the SOW and try the same get from %PSL

Let us know what happens.

The set command doesn't contain a time stamp the text from the log file does. The unique was just to remove redundant lines of the same error from the text file. Yes your right that the parameter is set in a different parameter, kind of. I am setting the parameter from a collector and attempting to retreive it's contents from the Notification area of Event Catalog 11 to send on to our SNMP management system. Here is the output.

I am really confused now Your original post shows that you are using three arguments for the set(). The third argument is meant to be a timestamp. You then indicated that the 3rd argument was a timestamp, and now you indicate that it is not? What is it? If the third argument to set() is not a timestamp I suspect that is causing the problem.

Let's copy this in your even notification action for event 11.

I think that will explain what you have to use to get the data you want ...

OK Mike, the unique(matchedline) is condensing multiple instances of the same line from a text file into one. Yes, those lines contain a time stamp. As you can see in my latest example I am able to extract the data from the parameter when in the collector. So don't focus on the set() command because it is working, the data is in the text parameter LogAlarms. The issue is, why can't I pull the data from LogAlarms when in  Standard Event Catalog 11.
