Cacti

We hit a little obstacle when trying to protect cacti using Shibboleth. We had to modify auth_login.php a bit to make login work with Shibboleth. First, change authentication to "Web Basic Authentication", then assign an user template from existing users in DB. Then in auth_login.php, we d...

mikee,

I have the same concern when I first start using cacti. So our workaround for this is instead of cacti issuing the heavy snmp or nrpe checks directly, we have cronjobs that pulls the data and save the metric in plain text. Then data input method is just a call to cat the file.

Hello! I just wonder if there is a way to add multiple devices of the same type (by the same host template) instead of adding it one by one. Thank you The super add plugin can add you host and graph fast although it doesn't support selecting host by host template. It's essentially web UI for theWit...

Maybe you can take a look at "Super Add" at my signature. It tries to solve the same problem except it uses cacti UI to do the work. But it doesn't automatically add data query graph and only works with 0.87+

Anyone got a solution to have different thresholds for the same data template. The idea is let's say we have different groups of server using the same data template, but would like different thresholds for them. The only way it can be done now is after creating the threshold from template, I have to...

I take "No it's not possible" for an answer as long as someone says something.

i did test it. great job! although i did change it to allow selecting only hosts from a host template. Thanks. I ran into a problem with your modification, it complains getHostsByTemplate function doesn't exist. Is that your own custom function? I get this problem with your original tgz also. Warni...

I don't know how others add dozen of hosts quickly, but for me, it's - Add device, select the right host template. - Go into each new host and hit 'create graph' link, select all graph and click create. Then repeat dozen times. If I added a new graph to a host template, then I need to go into each h...

I like the way how thold template makes putting threshold easier, but is there also some way we can put threshold on graph directly without associating threshold to any data source . I don't mean just applying cdef function to poller output. Specifically, I would like to use thold in conjunction wit...

I patch it to get this CDEF, total of DS value / total count of DS(NaN counts as 0) Here's the patch code for cacti/lib/rrd.php --- lib/rrd.php 2007-09-26 21:39:54.000000000 +0000 +++ lib/rrd.php 2008-01-10 00:11:17.000000000 +0000 @@ -956,16 +956,19 @@ /* make cdef string here; a note about CDEF's ...

To reply my own question, it looks like all my data sources for those graphs were gone after I aggregate them. I am trying to reproduce it again now.

I am pretty sure those graph I selected for aggregation where there.

Just install the plugin, everything works except rrdtool complained. cacti Version 0.8.6j aggreator = 0.64 plugin = 1.1 Looks like it doesn't have any DEF defined. I just picked couple graphs that's using the same graph templates and create a test aggregation graph. Where can I debug this further? t...

Sorry I couldn't find the code where the poller_output table is truncated, but I looked again in lib/poller.php, it has the same fall back value code in it which would still result in removing good values when it encounters a bad output. For whatever it's worth, I am attaching the diff for 0.8.6j fo...

cool! I will try the new version soon then.
