Hello,

I have a remote network with routers and switches from which I can poll lots of info like ARP/FDB...

Is there a way to add this info in Object Interface view ? In network map (I've tried to add end nodes and change radius : no success) ?

I just would like to create raw network maps of connected devices without doing a full discovery.

Thanks

ok,

I've recreate specific template per maker. What is the best way to duplicate a template ? Is it clever to export / do modification or merge modification /re-import ?

Is there some info on how we can modify templates by scripts ?

As I'm creating lots of settings (thresholds,...) I was hopping to be able to create template that can work with any devices, and move vendor specifics to another place.

what is the best to do this ?

Last solution may be to export one template,  modify the xml, and then re-import ? (not really clean, and don't know how the object IDs will match ?)

argrr...

Custom Attributes created in a template are not "visible" from script created in another one.

I've create a CA in HP template MaxMemoryOID = .1.3.6.1.4.1.11.2.14.11.5.1.1.2.1.1.1.5.1
I've bind a HP switch to this template.

And in a generic Switch template, I've create a dummy DCI to get SNMP value :
sub main()
{
trace(1,"Get CA=" . GetCustomAttribute($node, "MaxMemoryOID"));
snmp = CreateSNMPTransport($node);
return SNMPGetValue(snmp, GetCustomAttribute($node, "MaxMemoryOID"));
}

If CA is manually defined in the node : it works, if it is inheritated from first template : value is NULL.

Any idea to overcome this ?

Hello,

I'm creating templates for switch management. We have both Cisco and HP switches.
To handle this, I'm creating templates per Makers and template to handle DCI and other things.

Do you know if it is wise to use Custom Attributes to store specific OIDs ?

Is it possible to retrieve Custom Attribute values directly from SNMP DCI page ? or do I need to code transformation script for an internal dummy DCI ?

If a custom attribute is declared twice (ie : one on 2 templates attached to one node), is it possible to know which one will be used ?

QuoteTrace function should work. Do you get other debug messages in the log? Maybe you specify debug level higher then actually enabled?

Yes, I've opened a session on the server and tail netxmsd log file, I've also opened a server console and key in debug 1 (tried also for fun debug 9 : tail went crazzy).

QuoteDo your device supports 64-bit interface counters? When you do SNMP walk on .1.3.6.1.2.1.2.2.1.16 in MIB explorer, do you get results?

Yes I've made a try, and it founded values. I've reused the same settings with a regular interface OID, and it works so I really think issue is related with extended OID.

Quotedon't forget that instance discovery occurs at configuration poll

I'm doing my modifications, save, and close data collection configuration tab. I've also found that it is better to delete all the discovered DCI in the node Data Collection Configuration window before manually starting poll/Configuration on the node

Thanks,

Waiting for 1.2.8 

QuoteYou can create dashboard which contains other dashboards and configure rotation. (Create new dashboard object, add single element of type "Dashboard", open it's properties, and add dashboards you want to rotate to the list. You can also set delay between changing screen here.)

Seems to do the job, one question, I've create a dashboard to host network map. When it is displayed, I have no background, and icons are not setup like within the network map (I know that there's a bug with display settings storage not located in the map). Any idea ?

QuoteNo, with current map implementation you can only see different colors beneath object icon

Any schedule for creating decoration or other object with color selection linked to object status ? (it might be usefull for ATM monitoring )

Last thing : is there a way to send events to java console (like force opening X view) ? Thaks to this, it would be possible to change view when an event occurs.

Hello,

I'm trying to use Instance Discovery with SNMP values.

Is there a way to modify DCI description ? I wanted to add dci per interfaces, and currently I can just concatenate interface ID with a text. Is it possible to change $dci->description value ? I've tried to do this in the filter script with no luck.

I also tried to use trace function, but it looks to be inactivated

Last thing, I've tried to SNMP walk OID with this one : .1.3.6.1.2.1.2.2.1.16 (64bits values). I've got no result (I've cut and paste a config from Victor without success)

Thanks for your feedback

I've read last night a couple (lots) of threads, and it looks like I'm not alone.

We don't use vlan1, so it should be this. On my cisco switches (3750x and 2960s) only trunk or port channel including vlan1 are correctly linked.

Is this something logged in bugtrack ?

Thanks for your feedback,

Today we use zenoss to store all the info from our machines. It stores about 3 or 4 years of data which helps us to evaluate trends or forecasts.

Zenoss also use a template mechanism to create DCI (and associate a correct  polling interval). For instance, for each interface, we have in/out speed / packets /Errors, you can imagine how much it can be with 48 ports switches (or worst). Zenoss, just resample the data automatically, so you have a hour view, then daily, weekly and yearly. Of course we don't have a seconds resolution when we browse data 2 years old, but it is far enough to see trends.

I'm waiting for the snmp table implementation to prepare templates for switches, computers, printers, sensors (I'll share all the template), but storage optimization will be required to limit  the impact.

Is it easy to select all the DCI values with date filter and re-compute them ? (ie : take x values, compute average and replace the values by only one )
We could be something like :
-take the last week values, and compute average per hour
-take the last year and compute average per days (or half day)

Hello,

We would like to use netxms to provide a supervision Dashboards. I've started to create maps with equipment photos and status on top.

What are you using to do this (maps ?)? What is the best to display (html connection or full java console) ?

Is there a way to rotate screens (ie: switch some parts of the screen to see different info/room ?) ?
Is there a way to change dasboard screen when an alert is raised ? (an alert occured, and all the screens are switching to a view of the error DCI)
Is there a way to create icons depending on object status (we use labels, but sizeable lights would be easier to integrate on photos)

What is the use of rack object in Infrastructure Services ?
What is the best use of geo location ? (ie: I have multiple objects at the same location, do I use a container ?) ?

Thanks for your feedback.

I had (I guess) about 3 or 400 nodes founded.

I have done some reboot now and it looks like I haven't loose anything else (cross fingers).

the dbcheck returned nothing.

I think I've still got one issue, network toptology seems to be broken. I have some devices directly connected to switches (Cisco), but even after a Poll/topology, there's no link founded.

During one poll, I've seen a yellow warning message saying something like topology db locked....

Hello,

Wouldn't it be done with snmp tables ?

Regards

I see, but it will be a huge job to do this for mostly all the DCI...

How the retention job is working ? Is it some kind of daily Schedule ? If data are modified here, it will allow all the reporting feature to work as-is, and also it will be esier to handle the dozen (hundreds) of DCI per node ?
