Cacti

The problem was solved already within topic "weathermap 098a_cacti1.x_updated Page refresh issue" :) I was not aware that my problem was similar to the solved problem but the solution, described in "weathermap 098a_cacti1.x_updated Page refresh issue", works for me too. Sorry for...

I'm using Cacti 1.2.11 and had installed the Weathermap-Plugin provided by phalek (Very great, thank you phalek for adapting weathermap to Cacti 1.x ... :D ) I had defined some Maps which will all work without any problem. Only one issue is not working and I do not know the reason why. Maybe someone...

It might be helpful to share more informations about your configs to get help

This information has given me a good help to create queries ... I guess this might be helpful to you also

https://docs.cacti.net/howto:data_query_templates

You can try to define a CDEF like this:

1st CDEF:
a,b+,c+,d+ which will give you the Total of A,B,C,D

2nd CDEF:
e,f,+,g,+,h,+ gives you the Total of E,F,G,H

or all together:
a,b,+,c,+,d,+,e,+,f,+,g,+,h,+

Great. Thank you for sharing your solution

And the device, which is assigned to your DataSource, is the same on which you are running snmpwalk manually?

What about an PING which is running continously to check if the IP-connection between Cacti and the "External World" is available without interruption?
Maybe it's not an issue of Cacti / Poller

Hmm, looks all fine. One thing is confusing to me: I understand, in your first post, that you are capturing your data inside "rrdtool lastupdate /path/to/cacti/rra/mydevice_snmp_oid_555.rrd" Your graph, in your last post, was retrieving his data out of "... /srv/www/cacti/rra/________...

Can you share the Debug - Information of this graph?
Maybe this will give more background information for troubleshooting.

Yes, agreed with Witness. I seems you are not using only one template for your servers. Maybe you selected a different Template for your second server?
If you are using two Templates and you will stay on two Templates: it might be an idea to validate the configuration of both Templates.

Yes, I agree: regex101.com is a very nice tool I used it also to find a matching Expression for my needs .. but the REGEXP tested with regex101.com and also the results out of direct tests with php (as mentioned above) had not provided the result used as VALUE\REGEXP in Cacti. This is still a miracl...

Dear tertius, this was a godd suggestion. It is working and I can use it. I can get the string which is in between the "." and the right end of the String. Thank you. But I do not understand the VALUE/REGEXP in general :cry: .... after some search I found (I hope I'm on the right way) that...

Both of the last two Posts should provide the same results :wink: Maybe it makes sense to start with one Value as Area and three values as Lines. Only a CDEF which does the calculation '* 1024' Then compare the Current-Values with the Values shown in "top". If these values will match do so...

To me this calculation is not clear (I'm not an expert in CDEF): Values collected: a=mem_buffers b=mem_cache c=mem_free d=memTotalReal Is this the correct Calculation to get Memory Used? Memory Used = c,a,b,-,+,1024,* = (c + (a-b)) * 1024 The values on the Graph did not match with the values from &q...
