Thold precentage limits patch

[wwolkers]

Isn't it much easier to just create a CDEF for this?

put the max to 90 if you want 90%, and create a CDEF that calculated the percentage, no patching needed.

Hi wwolkers,

So can you explain me step by step how to make it work please ?

Thanks

[wwolkers]

apply my patch from http://forums.cacti.net/viewtopic.php?t=16054


then in the cacti interface click on graph management, then CDEFs

create a new CDEF, I called mine 'Diskspace percentrage'

add 5 items to this CDEF:

Item #1 Special Data Source: CURRENT_DATA_SOURCE
Item #2 Special Data Source: CURRENT_GRAPH_MAXIMUM_VALUE
Item #3 Operator: /
Item #4 Custom String: 100
Item #5 Operator: *

Save it! (how many times I haven't forgotten this after editing a CDEF )

then apply this CDEF to a threshold to test, and if it works apply it to all that you want a percentage monitored from, and apply it to your threshold template.

Good luck.

Thank you very much wwolkers ! It works fine for me !

note to "thold precentage limit pach" users - with the release of cacti-0.8.6i you should change factor parameter in check-thold.php to 8 on line 126:

126: $factor=8

Hi, johnrembo.
That looks good, but after I applied all patches, thold continue calculate values as a numbers, not percentages.
So I get picture like in attachment.
What is the problem?
I use cacti 0.8.6h with thold 0.3.0.

it is as it should be. precentage values are converted to digits only during pooling proccess(set $verbose=true in plugins/thold/check-thold.php and manualy run that file from command line - you will see how it works). i've not implemented those conversion functions anywhere else, because no-one requested for it ;]

I did manually run from command line(btw. there isn't variable $verbose, only $debug and $show), that what I'v seen:

Code: Select all

Checking Threshold : "host - Used Space - /var"
     Data Source : hdd_used went above threshold of 100% with 482560000

I don't see from this how comparison occur...
And those values are far from 100%.
Any ideas why is it being triggered?

hi wwolkers

i had try your method it successfully converted the data size into percentage, but the percentage always 100%, which means the

CURRENT_DATA_SOURCE = CURRENT_GRAPH_MAXIMUM_VALUE

so i remove the CDEF setting, then the thold data became data size again, it shows the used_size

is that mean, the CURRENT_GRAPH_MAXIMUM_VALUE cannot grap the graph value ?

please kindly advise

i think you've replied to wrong subject.

[johnrembo]

you had to look in patched section, not in beginning of the file:

Code: Select all

//------------------------------------------------TPEP BEGIN-------------------------------------------//
if ((stristr($item["thold_hi"],"%") or stristr($item["thold_low"],"%"))==true) {
	$verbose=true;//info about percentage evaluation proccess (php check-thold.php)

check the code between "___TPEP BEGIN___" and "___TPEP END___". Shortly it does the following:

if upper_limit(80% for example) contains % sign, then it must be replaced with the following:

Code: Select all

80%->80*graph_template_upper_limit/100

it is as it should be. precentage values are converted to digits only during pooling proccess(set $verbose=true in plugins/thold/check-thold.php and manualy run that file from command line - you will see how it works). i've not implemented those conversion functions anywhere else, because no-one requested for it ;]

Please, when i apply the CDEF "relative percentage" in my treshold i see one message error :
CDEF property not implemented yet: ALL_DATA_SOURCES_NODUPS,

And the values are long number like 1904673.67 and the value correct should be 95.04.

Howto resolve the problem ?


Thanks.
