SNMP v3 isn't hardcoded. I used "universal" script for all version of snmp. It will be used version, which is selected in cacti. I think, that ESXi use 1/2c only. You cannot use v3.bogd wrote:This is great -thank you!!
One small problem, though - the PHP script getting the VM info (ss_esxi_vhosts.php) is hardcoded for SNMPv3. Could someone help me get this to work with SNMPv3?
The script calls cacti_snmp_walk, and changing that to use SNMPv3 seems possible. However, I do not know enough about the inner workings of Cacti to send all required information to the script - it will need a username, password, priv_pass, etc.
Thank you!
[ Edit: there seems to be something wrong with the script (or with my ESXi server). Even after enabling SNMPv2 on the host, there is no vmwVirtMachines OID (enterprises.vmware.2) - and since the script uses it to get all info related to VMs, there's nothing there.

You can try change template version hash. Howto is here http://docs.cacti.net/howto:determine_c ... te_version.alkocelj wrote:Could you please export this template that this would work on Cacti version 8.7g?
Thx
Alex
Try attached template. I reimported template only, It isn't tested on 0.8.7. If it fails, update your cacti instalation.alkocelj wrote:I have tried and did not work. Maybe I am doing something wrong but I cannot import it.
You are right. ESXI 5.0 uses different status. I fixed it, please download version 0.2 and overwrite file ss_esxi_vhosts.php in cacti_instalation/scripts/.biohazard wrote:The vhosts graph looks great except the running hosts measurement always shows 0. I have 5 virtual machines running, 3 with tools 2 without.
Running ESXi 5.0

The vhosts graph is reporting 0 for everything. I changed the log level to debug in cacti and there doesn't seem to be any errors. The values returned are all zero.

Using your snmpwalk suggestion, the info in this thread and a little luck, I figured this one out myself. Like another user, when I did an snmpwalk, I got something like this:macan wrote: I haven't 5.5 U1.Can you send me snmpwalk of your ESXI 5.5 U1?
I think I have a workaround. Long story short, use your work to get the data, delete the graphs (but keep the data sources) and use something like this: https://bryanfullerton.com/2009/08/04/c ... e-machine/macan wrote: I didn't find this value
Does vmware expose anything from esxtop, specifically stuff from d (disk adapter) or u (disk device)? Maybe graph commands per disk adapter (I use software iSCSI so i only have one vmhba that gives me any data) or mb read/write? I tried to read the mib files and it seems like the answer might be no (I found this nagios page which seems to indicate I would have to go the api route to pull any more detailed info: http://exchange.nagios.org/directory/Pl ... pi/detailsmacan wrote: Ok, send me your requests
Interestingksdjfh wrote: No 6876.2 which is what you're using to pull data. Originally I configured the /etc/vmware/snmp.conf file by hand which I guess ESXi didn't like.
To fix the problem I did:
esxcli system snmp set --reset
esxcli system snmp set --communities public
esxcli system snmp set --enable true
Then when I did an snmpwalk I got a lot more values and the graph started pulling data.

I found that page about a year ago and used the info on it, and the page it links to in order to create the graphs I needed.
I think, that answer is no. It isn't posibble to use SNMP for this. You have to use another way. Maybe ssh key exchange on cacti and pull data via script like:ksdjfh wrote: Does vmware expose anything from esxtop, specifically stuff from d (disk adapter) or u (disk device)?

Do you know how to do this? I've been trying to get the graph I want but I'm going in circles. I can create a basic aggregate graph and convert the area to line graphs. My problem is I would like to see an extra line on there to show the average (or maybe even hide all the individual cpus and just show a line for the average). Also in the legend, I do not want to see CPU1, CPU2, CPU3, etc. It gets very long when you have 20+ cores. Just want to see the total average of all cpus.macan wrote:Do you know http://docs.cacti.net/plugin:aggregate?ksdjfh wrote: I think I have a workaround.

Hi, I prepared multicpu avg tempate. There is one line line - avg load for all cores.ksdjfh wrote: Do you know how to do this? I've been trying to get the graph I want but I'm going in circles.
