oh my god... I spent hours assuming green was active. I'm sorry to be a hassle and thank you so much for pointing out this blunder...

Hello I am new to cacti and intro page and was wondering if there is a way to make a graph that is in the same format as the Devices by Status graph on the default panel.

[macan]

It isn't possible now. Cacti graphs are using rrd and other graphs on intropage uses js library.

The alternate graphing engine is something I've given some thought to in recent days. It's something I wrote already using a not so open source graphing solution in the past, one that had it's own templating API and not Cacti's. The new API should simply turn Cacti's LINE:AREA:STACK into objects to be fed to the charting solution I have in mind. Right now, though Billboard is awesome, I'm leaning more towards ApexCharts, though until I dig in, I won't make that final decision.

Hi guys @macan, i need some infos related to new control "not optimized Bulk Walk Size devices".

This is my result:

how can i use this information?

i have made some checks but i didn't see problems related to devices with:
xxxxx - (xxxxx) (ID: 12, Bulk walk size: -1)

can you help me? thanks a lot.

xmacan, maybe we need a tip for each issue. This one is a bit more complicated to resolve. Basically, the Auto-Detect on Reindex turns out to take much more time for a re-index operation. It's better to set to Auto-Detect and Set at First Re-Index as it can greatly reduce the amount of time to perform a Re-Index.

In my scenario this is the result of re-index output:

Code: Select all

Total: 0.000000, Delta: 0.000000, Auto Bulk Walk Size Selected.
Total: 0.030000, Delta: 0.020000, Tested Bulk Walk Size 1 with a response of 0.0239.
Total: 0.030000, Delta: 0.010000, Tested Bulk Walk Size 5 with a response of 0.0061.
Total: 0.030000, Delta: 0.000000, Tested Bulk Walk Size 10 with a response of 0.0030.
Total: 0.040000, Delta: 0.000000, Tested Bulk Walk Size 15 with a response of 0.0034.
Total: 0.040000, Delta: 0.000000, Bulk Walk Size selected was 10.

it seem to be no problems but the device is still flagged as problematic.

If you run this query, the problems should be resolved:

Code: Select all

UPDATE host SET bulk_walk_size=0;

Then it'll lock in at 10 for ever afterwards.

the witness this field/parameter shouldn't be automatically updated after every re-index?

done, it works.

Once you've detected it once, unless something changes where it's not performing as well, there is no need to do it again. A case where you might want to set it to -1, is to see if it changes over it's life, or you get a firmware update to make it work better at larger bulk walk sizes.

i have see after modification of the db string "UPDATE host SET bulk_walk_size=0;" an substantial increase in page opening and reading speed, probably when this parameter is set to "-1" slowing down db read.

intropage is a fantastic plugin, thanks a lot for your constant support to develop it. the last check introduced the "bulk size" keep me in the direction for resolve some problems to slow db read. thanks a lot.
