QlikView SNMP error

[#1]

Hi

I'm having problem with QlikView and SNMP. Not 100% sure what to call the program since the problem is with our clients server and we're hosting it. Server is Windows Server 2012 R2 and programs and features shows these apps installed:

QlikView NPrinting Designer

QlikView NPrinting Server

QlikView Server x64

QlikView X64

And for the actual problem: we cannot monitor this server (where QlikView is installed) with SNMP. I've tried few tricks which I found on this forum, but still cannot get SNMP working. I am 100% sure that this is because of QlikView, not networking, firewall / other problem.

Tried these tweaks:

- Disable SNMP support for QlikView Server service, add "EnableSNMP" registry key (REG_SZ) in HKLM\SOFTWARE\QlikTech\QlikViewServer\Settings 7 and set it to 0 (zero)

- In v10 to disable SNMP, add the following string in the QlikView Server configuration file ( [Settings 7] paragraph of C:\ProgramData\QlikTech\QlikViewServer\Settings.ini ) => EnableSNMP=0

Also everything what reads in here:

Can I switch off SNMP on QVS?

Re: Disable SNMP in qlikview?

Disable SNMP for QlikView server

Still no go. Any help from you guys or new things / tricks which I could try? Help would be greatly appreciated!

Still trying to figure this out

Could you tell what is actually returned when you request a respond?

Also, could you specify the versions of the Qlik products installed?

See also

SNMP ‒ QlikView

where you may find more information about SNMP configuration for the different QlikView services.

From successful response I get FQDN of the server, ie: hostname.domain.com

Unsuccessful response I won't get FQDN. Error report:

Error executing snmpget to [IP] on [SNMP_AGENT] (Error: JavaException: net.basen.scriptutils.ScriptableException: [IP]: No SNMP response. Timeout=2000ms, retries=1. Tried with SNMPv2C and SNMPv1)

SNMP community is correct and OID is: 1.3.6.1.2.1.1.5.0

Versions of programs are:

QlikView x64 v. 11.20.12235.0

QlikView Server x64 v. 11.20.13206.0

QlikView NPrinting Server v. 16.0.0.0

QlikView NPrinting Designer v. 16.0.0.0

Doh, it's been a while since I last tried to get SNMP working on a Windows/QlikView server (and my notes from that time are located somewhere else).

But what I remember from those experiments is this:

• It's either Windows or QlikView you can monitor using SNMP, not both
• If you want to monitor Windows, you should first install the services and enable them. Then you need to configure your firewall settings, otherwise requests will be blocked.
• AFAIK QlikView SNMP isn't enabled by default, but that may have changed in recent product releases.

Best,

It's either Windows or QlikView you can monitor using SNMP, not both

* It's absolutely Windows which we want to monitor

If you want to monitor Windows, you should first install the services and enable them. Then you need to configure your firewall settings, otherwise requests will be blocked.

* Windows services are installed (SNMP Service + SNMP WMI Provider) and working. Tested with Paessler SNMP Tester 5.2.3.

* Firewall is configured to allow UDP on both directions (in/out) to our SNMP agent hosts (=from where we send out SNMP requests). Also there is a rule to allow SNMP protocol to both directions to these same SNMP agent hosts.

AFAIK QlikView SNMP isn't enabled by default, but that may have changed in recent product releases.

* I put 3 links into my first post and tried to disable QlikView SNMP service from everywhere I could find. SNMP is still not working.

Have you tried disabling all QV services and restarted the system? Just to double check that QV is really causing the issue.

You can also explicitely specify ports different from 161 for QV SNMP (as described in your referenced threads and the Help docs).

If I stop all QlikView services and restart computer, will those services still be stopped after restart? Server is hosted so I have to ask permission for reboot, so I'm making sure those services are staying shut down after I stop them.

I tried restarting computer earlier, don't remember 100% every trick I tried then..

Well this is interesting. I disabled all QlikView services (after I stopped them of course) and restarted server. Tried getting SNMP response from agent. No answer. I can however get an answer when checking locally with Paessle SNMP Tester, so SNMP is surely working. I even tried stopping Windows SNMP service -> tested SNMP -> indicated SNMP is not working -> started SNMP service -> tested SNMP -> SNMP OK.

I'm really puzzled about this.

[Peter_Cammaert]

Well, that may not be entirely unexpected. SNMP is a device management protocol, not only a reporting protocol. As a result, it usually doesn't travel WANs/internets well because that would be an invitation to hack your devices. SNMP is not very secure.

In your OP, you were talking about "hosting" these QlikView services for your customer(s). Do you have VPN access to this hosting environment? If so, check whether SNMP works through a tunnel. If not, you may still have work to do in your firewall configuration. Note that - depending on the complexity of your network(s), there may be a firewall device between subnets that blocks SNMP traffic. So Windows firewall may be open to all queries, but your network may still block them.
