I've finally decided to test out cacti-0.8-pre20030508 on a small installation at my company's office -- waiting for full release before rolling out to client sites..

First off, Excellent job with the templates for the Netware servers. It may be worth noting somewhere that sys:system/nma/nma5.ncf should be run in autoexec.ncf on the netware servers so that all this data in SNMP becomes available.
NMA5.NCF:

Code:

Load NMA\HostMIB
Load NMA\ServInst NoSAP

I went through the Add polling host screens to add a Netware server, using the Netware host templates -- very nice.. However, at the end (after the create graph screen), it should return to some other screen with a success message rather than the "Polling Hosts [edit: <NetwareServer>] " screen. I thought it was a little odd coming back to this configuration screen that I had already been through.

Do not show a "logout" button unless the user is logged in.

On the Volume information graph template, the total space should be the first graph item ... By default, it came up as the second item after the free space. This means that the free space area was "behind", not visible, the total space area.

Can you make it so that CPU information automatically creates all necessary data for multiple CPUs ? Similar to the way you iterate the volumes & create their respective traphs. And, each CPU would have a different colored line on the same graph.

Also, when deleting an item, you have "Cancel" and "Create" on confirmation screens .. The "Cancel" is appropriate (possibly replaceable by "No"), but the "Create" should definitely be replaced with a "Yes" button.

I'd love to something similar to the Netware Templates for Windows servers! (Yeah, I know Gates & his crew have done nasty things to SNMP support on the servers that severely limit the available info.. but SNMPBoy's PERFMIB tweak provides a pretty good set of info that I've used on several WinNT4/Win2K servers).

I am sorry for not getting to this sooner. I did in fact read this post a few days back, but I usually like to let feature request posts "sit" for a little while so I can decide what would be best.

This is a useful suggestion, but I am not sure the best place to put it. Where could I put something like this, so that users would see it before attempting to graph their Netware boxes?

I take it you mean on the graph viewing screen. I will make sure to fix this.

I fixed this on my local database, it will make its way into cacti.sql shortly.

I could do this if Netware provides this information in a parsible format. I am able to retrieve a list of Volumes because Netware provides each volume via SNMP and gives it a unqiue index value. Is the same true for CPUs as well?

I agree with you here. Perhaps I will replace these with "Yes" and "No" buttons.

You're right, the default SNMP under Win2K sucks

. There has actually been some interesting development about retrieving statistics from a Win2K server using WMI and Perl. There is not much preventing me from including such scripts/templates in Cacti now, just some time I guess. I am also not sure if these Perl scripts would work under a Unix-based environment.

I will take a closer look at the PERFMIB that you mentioned. That is definitely a viable option as well.

Let me know if you have any further suggestions.

Going back through these steps, a couple options come to mind...
1. Some sort of JavaScript that gets activated with each selection in the drop down box gives notes regarding that particular selection. (I prefer this one of the two because it's a more immediate notice regarding the special needs of the selected host template).
2. Add to the documentation. I'm sure this should be a given.

I think the most appropriate destination would be back to host.php, as if the user clicked "Polling Hosts" in the Data Gathering menu. This way, they see their new addition in the list and know that was added.

You've prompted me to help a little more

-- I dug up the MIB browser on one of our dual-processor Netware 6 servers... Here's some useful info:
.1.3.6.1.4.1.23.2.27.3.3.0 = Processor count
OBJECT-TYPE iso(1).org(3).dod(6).internet(1).private(4).enterprises(1).novell(23).mibdoc(2).nwHostExtensions(27).nwhrDevice(3).nwhrProcessorCount(3)

Processor Table: .1.3.6.1.4.1.23.2.27.3.16.1
iso(1).org(3).dod(6).internet(1).private(4).enterprises(1).novell(23).mibdoc(2).nwHostExtensions(27).nwhrDevice(3).nwhrProcessorTable(16).nwhrProcessorEntry(1)
Next Objects under this OID:
nwhrProcessorIndex(1) -- A unique value for each entry in the table .

nwhrProcessorNum(2) -- Processor Number .
nwhrProcessorStatus(3) -- Status of this processor .
nwhrProcessorUtilization(4) -- Processing load on this processor for the last second , expresses as a percentage .
nwhrProcessorInterrupts(5) -- Number of interrupts fired on this processor in the last second .
nwhrProcessorIntTime(6) -- Amount of time that the processor spent processing interrupts in the last second , expressed in microseconds .
nwhrProcessorThreads(7) --

Sample output.. starting with the last entry before the processor table:

Code:

enterprises.23.2.27.3.15.1.15.8 = 0
enterprises.23.2.27.3.16.1.1.1 = 1
enterprises.23.2.27.3.16.1.1.2 = 2
enterprises.23.2.27.3.16.1.2.1 = 0
enterprises.23.2.27.3.16.1.2.2 = 1
enterprises.23.2.27.3.16.1.3.1 = 1
enterprises.23.2.27.3.16.1.3.2 = 1
enterprises.23.2.27.3.16.1.4.1 = 0
enterprises.23.2.27.3.16.1.4.2 = 0
enterprises.23.2.27.3.16.1.5.1 = 178034079
enterprises.23.2.27.3.16.1.5.2 = 347894134
enterprises.23.2.27.3.16.1.6.1 = 534796
enterprises.23.2.27.3.16.1.6.2 = 1435626
enterprises.23.2.27.3.16.1.7.1 = 53
enterprises.23.2.27.3.16.1.7.2 = 56

So, for each CPU, there are corresponding entries for each OID .. at the moment this SNMPWALK was performed, both CPUs were at 0%

I think I get it... Just a few minutes I'll post a netware_cpu.xml file for resources, I think I understand the syntax...just not sure what to do from there -- have at it Ian.

I will probably end up adding it to the documentation... at least initially. Just need to find a place for it now

I made this change, let's see how it goes.

Using all of the very useful information you provided, I added 'netware_cpu.xml'. I also added this to the default cacti.sql database and tested it on a Netware 5.1 box I have access to. Works great, thanks!

Let me know if you find anything else, the release is going to happen very soon
