network traffic windows, semi automatic perf counter

[flexguy]

should speek for itself:

'VBS script to "almost" automatically insert PerfCounters in
'your zabbix_agentd.conf for monitoring network traffic on a windows machine
'
'item in zabbix should be:
'type: active agent
'key: nic_in (our nic_out)
'info: float
'translate Bytes Received/sec & Bytes Sent/sec to your locale
'edit strFileName to your needs

Dim colAdapters, objAdapter, NicDescription, strFileName, objFS, objTS
Set colAdapters = GetObject("winmgmts:{impersonationLevel=impersonat e}").ExecQuery _
("SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled = True")
For Each objAdapter in colAdapters
NicDescription = objAdapter.Description
Next
strFileName = "C:\zabbix_agentd.conf"
Set objFS = CreateObject("Scripting.FileSystemObject")
Set objTS = objFS.OpenTextFile(strFileName,8)
objTS.Write vbCrLf

I'm curious, what is the advantage of adding the perfcounter strings to the agent conf file?

[gospodin.horoshiy]

Great idea,thanks! But it only works if I change:

Set colAdapters = GetObject("winmgmts:{impersonationLevel=impersonat e}").ExecQuery _
("SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled = True")

to


Set colAdapters = GetObject("winmgmts:{impersonationLevel=impersonate}").ExecQuery("SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled = True")


And it only adds single interface. Is there anyway to add all interfaces?

[gospodin.horoshiy]

Here is how I've modified the script,so it adds all NIC you have:

ALSO:
'NicDescription(4) is here because of my lack of scripting experience. Calling 'someone to modify it to change digit 4 to number of NICs
AND:
I used different class: Win32_PerfFormattedData_TCPIP_NetworkInterface (thanks to mpeide) , because it returns names in format used in perfmon not windows: Example Intel[R] instead of Intel(R)

Sorry about that typo in "....el=impersonate...".
I did too adjust the script to add all IP interfaces (see below). I do have some scripting experience, and my script works perfectly without the refresh stuff. Thanks anyway for the cooperation.

Never mind!! I figured out what to do and what I was doing wrong.

I used nic0_in as a key BUT I didn't wait long enough



======= Ignore the rest of this!!! == I'm dumb ==

I just tried this and it does correctly place the information in the conf file:

PerfCounter=nic0_in,"\Network Interface(AMD PCNET Family PCI Ethernet Adapter - Packet Scheduler Miniport)\Bytes Received/sec",60
PerfCounter=nic0_out,"\Network Interface(AMD PCNET Family PCI Ethernet Adapter - Packet Scheduler Miniport)\Bytes Sent/sec",60

AND Zabbix_agentd.exe does seem to create the "alias" as per this item in the log:

2268:20090312:130129 cfg: para: [PerfCounter] val [nic0_in,"\Network Interface(AMD PCNET Family PCI Ethernet Adapter - Packet Scheduler Miniport)\Bytes Received/sec",60]
  2268:20090312:130129 Accepted configuration parameter: 'PerfCounter' = 'nic0_in,"\Network Interface(AMD PCNET Family PCI Ethernet Adapter - Packet Scheduler Miniport)\Bytes Received/sec",60'
  2268:20090312:130129 In add_perf_counter() [name:nic0_in] [counter:\Network Interface(AMD PCNET Family PCI Ethernet Adapter - Packet Scheduler Miniport)\Bytes Received/sec] [interval:60]
  2268:20090312:130130 PerfCounter nic0_in: "\Network Interface(AMD PCNET Family PCI Ethernet Adapter - Packet Scheduler Miniport)\Bytes Received/sec" successfully added. Interval 60 seconds
  2268:20090312:130130 Alias added. [nic0_in] -> [__UserPerfCounter[nic0_in]]
  2268:20090312:130130 cfg: para: [PerfCounter] val [nic0_out,"\Network Interface(AMD PCNET Family PCI Ethernet Adapter - Packet Scheduler Miniport)\Bytes Sent/sec",60]
  2268:20090312:130130 Accepted configuration parameter: 'PerfCounter' = 'nic0_out,"\Network Interface(AMD PCNET Family PCI Ethernet Adapter - Packet Scheduler Miniport)\Bytes Sent/sec",60'
  2268:20090312:130130 In add_perf_counter() [name:nic0_out] [counter:\Network Interface(AMD PCNET Family PCI Ethernet Adapter - Packet Scheduler Miniport)\Bytes Sent/sec] [interval:60]
  2268:20090312:130130 PerfCounter nic0_out: "\Network Interface(AMD PCNET Family PCI Ethernet Adapter - Packet Scheduler Miniport)\Bytes Sent/sec" successfully added. Interval 60 seconds
  2268:20090312:130130 Alias added. [nic0_out] -> [__UserPerfCounter[nic0_out]]

BUT I cannot determine the right key to use in the frontend. All that I try comes up as not supported and I have restarted my agent (I realized that I had forgotten to do that first after a few tries ). I can't seem to find it in the documentation and I haven't found any thread that explicitly says what to use. Maybe I just missed it.

Please, what would I use as the key in the frontend or do I have something else wrong?

Thanks in advance

[flexguy]

what key to use

jrobertson,

True, after ALL changes to your agent configuration file you have to restart the agent. I did find out the hard way also...

Did you use the settings described in the first few lines of the script:
type: zabbix agent (active)
key: nic0_in
type of info: float

some pitfalls as why this won't work:

- hostname in conf is not exactly the same as the hostname in zabbix server
- active agent is not enabled on monitored host
- firewall rules prevent active agent from connecting to server

I guess the whole thing works in passive mode too (didn't try yet)

Good luck,
