NPM polling interval is applied but not effective.

Hi All,

I have an issue with Orion NPM that is giving me headaches for a few weeks (I am using v10SP1, issue was the same with v9.5).

I have defined status polling interval to 60s for all my nodes, but I keep getting only one response time value every 3mn in the database.

This is what I get when I do a request in the DB for a random node :

SELECT PollInterval FROM Nodes where NodeID = 3100;

Select top 5 datetime from ResponseTime_Detail where NodeID = 3100 order by datetime desc;

2010-12-29 23:03:31.997

2010-12-29 23:00:31.997

2010-12-29 22:57:17.000

2010-12-29 22:54:15.000

2010-12-29 22:51:18.000

I can see in the database how it happens, but I cant explain it :

1) At t=0, a poll is done. The "NextPoll" value for that node is changed to t+1mn.

2) At t+1mn nothing happens.

3) At t+2mn still nothing, but the "NextPoll" value is changed again to one minute in the future (so t+3mn)

4) At t+3mn, the poll is done (and so on).

Processor use on polling engine never go above 25%, and disk queue on DB server stays ridiculously low. Polling completion is over 99%.

I have 6k6 "pollable" items (nodes, volumes, interfaces), which would require 6600/60=110 polls per second, and i use 186 pps (recommended values of pps tuner tool).

I dont know what to do anymore, I totally ran out of ideas... please help

Thats a good question and I was ready to provide an answer, but my answer does not seem to be working!

Normally, if you change the node polling interval on the Polling Settings page of the Orion web console, then click on "Re-Apply Polling Intervals", the new polling interval should be written to the PollInterval field in the Nodes table of the database.

However, I see that my polling interval values are not changing in the database.

Why are the new polling intervals not reflected in the Nodes table, but they are on the website?

Additional information.... I can change the Rediscovery Interval on the website and it will change the value listed in the Nodes table. I can also change the polling interval for interfaces and I see the new value in the Interfaces table as well.

Right now, the PollInterval field in the nodes table will NOT change to the new value set on the web site.

What gives?

I had same thing in the past, the mistake I was doing is not submitting the new values before.

To change the default values, you must first submit it (at the bottom of the page) then you can re-apply it on objects.

Nope. Does nto work for me. No matter which order I click Submit or Re-apply buttons, the Polling Interval for nodes does not change in the Nodes table of the database.
