Cacti

I have the thold module installed, however have a problem every time I try and go into the thresholds section - I was watching the query being run, and ran an explain on it: explain SELECT DISTINCT field_name FROM data_local AS dl INNER JOIN (SELECT DISTINCT field_name, snmp_query_id FROM host_snmp_...

The main two issues that I'm trying to work around involve the information being returned by the device when you are gathering information such as the ifDesc/ifAlias and ifSpeed. For example, one of the ATM devices I am working with uses multiple physical T1 lines to create a larger aggregated inter...

My current issue is that i'm polling ~2800 devices, each with at least 10 interfaces, and they respond slowly to SNMP, so i'm having to start a large number of script servers each poll period. They're also not always closing correctly, tying up resources. I'm going to try and tackle it from a differ...

I have a large number of devices where I have to use a script to work around issues in the results being returned via SNMP (for example, an ATM interface that shows as one physical interface and 3 sub interfaces .. you have to poll one of the sub interfaces for traffic stats but the description is o...

Just checking if anyone else is seeing this problem: Just installed 0.35b5 under an copy of cacti v0.8.7g. I go into 'Tree Rules', click on 'Add', enter a name and then change the 'Tree' dropdown to a different tree. The page then automatically reloads and the 'Tree' setting has reverted back to the...

IIRC, you need to use GNU patch (gpatch) instead of the system patch under Solaris.

Is there any reason why the >=, >, < and <= operators (when creating rules) are using string comparison, rather than numeric comparison (or at least offering you the choice to use string vs numeric) ? The reason that I ask is that I'm writing some graph rules based on whether ifSpeed is greater than...

use 'chmod 2775' on the rra directory, making sure that the rra directory has the right ownership. (similar to running chmod g+s)

Has anyone already implemented tracking the number of NaN values for a given time period? It would be useful when you want to validate that all the data sources are gathering information correctly?

[1] [2] Now I saw that my CACTI consume more memory (RAM) and no more practically available memory: IS MY POLLER SETTING CORRECT ? or I need to adapted it ? top - 17:32:56 up 3 days, 1:43, 1 user, load average: 0.09, 0.17, 0.21 Tasks: 239 total, 1 running, 238 sleeping, 0 stopped, 0 zombie Cpu(s): ...

I'm trying to set up an interface utilization % threshold monitor, using the rrd_maximum instead of ifSpeed (for situations where ifSpeed would be incorrect, such as 10Gb interfaces) It wasn't working the way I was expecting, so I tried to set up a CDEF that would just return the rrd_maximum: cdef=C...

Ahh, found what I was looking for: CURRENT_DS_MAXIMUM_VALUE

Is it possible to use the value of the 'largest possible value' in a graph template? What I am trying to do is add a 'total bandwidth' label on several interface utilization graphs. Previously i've been using |query_ifSpeed| in a CDEF, however i've now got some devices where the ifSpeed is inaccurat...

We're seeing a similar issue, were running spine 0.8.7d, upgraded to e + patches, now using the debug server php file. I'm getting a large number of these lines a second: 10/01/2009 11:37:50 AM - SPINE: Poller[0] ERROR: SS[0] PHP Script Server communications lost. Restarting PHP Script Server 10/01/...

Actually I'm not sure you can do what I was needing just using the cacti framework as is. To give you an example of the SNMP walk information: RBN-SUBSCRIBER-ACTIVE-MIB::rbnSubsEncapsCount.ppp = Gauge32: 50 subscribers RBN-SUBSCRIBER-ACTIVE-MIB::rbnSubsEncapsCount.pppoe = Gauge32: 50 subscribers RBN...
