SIM agent ver 7.0 and snmp

Andy Milewski — Fri, 13 Feb 2004 16:26:11 GMT

having a problem with my IM agents after minimal usage. SNMP is not being read for config info although community string hasn't changed. When I first launched agent homepage, all info, categories existed. Now after several reboots of the system and even trying to login and go to snmp setting only the vc info comes up. homepage loads slow and navigation is slow. java 1.4.2_01 on the system. is there a file that I an verify/edit that holds the snmp info?

If I understand you properly, you go to the device's web page at http://SERVERNAME:2301 (or https://SERVERNAME:2381) and the only thing you see is the version control info.

Have you checked to make sure that the Insight agent services are running? (Foundation agent, NIC agent, etc) That is what will account for the missing categories, not SNMP. Also check the Windows event log for evidence on why they aren't starting.

Also, what is the OS?
"Reading a config file for SNMP" sounds a bit like Unix.

agents are running;
w2k sp4.
wondering if IM agents have a config file that would maintain info around snmp community string

No, the SNMP stuff is quite separate from the Agents, but the Agents rely on SNMP connectivity. All SNMP stuff is configured from the SNMP Service in Windows.

I've overcome some issues by restarting SNMP and all dependent Services, which restarts all of the Agent Services. Once done, try browsing to http://Server:2301 which should then flip you to https://server:2381.

back on this issue after a bit of a delay.
I have added a new community string entry to the SNMP service on the Windows 2000 node. Done a restart of the service which also restarts the IM agents. I still have not data other than the VC agent. I have also manually restarted all services for IM: server agent,web agent, etc. If I am understanding one of the responses, the community string is not stored in any files used by the IM agents. Is that correct? seeems that if there is a choice for setting the community string when in the Homepage, that it is stored either in registry or in a file. any other ideas.

Andy,
I guess it's stored in the Registry. SNMP is totally separate from IM and teh agents in this respect. You can change the SNMP Settings from the IM Agent.

On a W2000 Server SNMP is configured from the Services GUI, the last three tabs in the Properties box.

There needs to be a matching community name on the Client end, and to provide full functionality this needs to be read / write as a minimum.

Rob,

the service tabs is where I have made my changes. This is a real show stopper for me. I am an internal HP Openview employee who develops and runs a demo center in FC Colorado. Is there somewhere internally I can turn for help. My community strings have at least read/write access. I have restarted agents after making changes to SNMP but am not really making any progress.
Any suggests?

Rob,

looks like if I use a community string of public things work as expected. As soon as I make a change, SIM and its agents no longer like the SNMP. I can not add additional community strings in addition to public to the service either. I need to use something other than public since other software I am running requires different strings.

You can have multiple Community Strings on the SNMP Agent.
I'm trying to remove the Public one from my Servers, but in some cases I have that and the additional Read/Write Community string.

I'm not sure if they're case sensitive or not. You also need to configure HPSIM to communicate on different Community Strings, it's under Options / Protcol Settings / Global Protocol Settings.

If I set to public, the homepage works. If I add an additional community string or change to something other than public, homepage no longer works. I am always using at least Read-write. I will be interested in the outcome of your changing your community string to something other than public

Re: SIM agent ver 7.0 and snmp

Rob Buxton — Mon, 01 Mar 2004 15:39:46 GMT

Andy,
I've already done it and it works.
You just need to ensure the Community name is set up on both Servers.
On Servers in our DMZ, I've removed the Public Community name.
I've added a new Community name for IM on to the SNMP Client. I also configured HPSIM with that community name. So that still has public as one of the Community names plus my additional ones.

I can't recall if I needed to rerun the Discovery or Identification tasks, but it's always worth a go.

Andy Milewski — Mon, 01 Mar 2004 15:51:56 GMT

strange. I am in a HPQnet DMZ and am not having the same results. DNS works fine(I have full control over DNS) In fact, if I change the community string to public and log on for the first page to the agent homepage, I get info as expected. If I log off and log back in, the info is not displayed properly until I restart the SNMP service. If I have any other community string things don't work and if I have the public default string and another community string things also fail. any ideas how I can troubleshoot this further

Andy Milewski — Mon, 01 Mar 2004 15:54:42 GMT

Rob,

what happens if you log in to the agent homepage, log out and then log back in to the agent homepage again after changing the community string?

looks like discovery and SIM are working for me but not the agent Homepage.

Andy,
I've not tried that but access to the Web Page is independent. The SNMP connectivity allows IM to establish connections and get data but simply logging directly onto the Agents Web Page will always ask you for the credentials as it's not from a trusted source.

I'm also having the exact same error. I removed IM reninstalled reconfig the snmp info and all I can display is the version control information

Andy Milewski — Tue, 02 Mar 2004 16:35:35 GMT

Chris,

I still don't have resolution to this issue. I do have a call in with HP support. Do you have any Openview apps on your system? any apps that are heavy SNMP users?

Re: SIM agent ver 7.0 and snmp

Chris Zehr — Tue, 02 Mar 2004 16:44:56 GMT

currently I'm using SNMPc from Castlerock Software to manage about a 100 devices.

Re: SIM agent ver 7.0 and snmp

Chris Zehr — Tue, 02 Mar 2004 17:14:16 GMT

I went into snmp service
Security tab
selected accept snmp from any host

it begin to work

I then added 127.0.0.1
and my nms

after I updated the VC
it stopped working again

so I selected accept from any hosts and it begins to work again.

if life were so easy for me. unfortunately whether I allow all or set loopback and even local IP like you did mine still does not work. what happens if you log out, then back in to the homepage. On mine, I get access one time before I have to restart one of the snmp related agents
