Riedel SNMP Agent for Artist - has anyone used it?
« on: August 03, 2015, 05:56:46 PM »

This is system monitoring software.  However due to little documentation on the Riedel website, it appears that it cannot really monitor anything about artist that you can also see in director. 

Specifically we want to query the actual temperature in the nodes, not just alarm severity.

The problem may be that Riedel's SNMP only supports Option 1 and not 2&3 which include quantitative variables but I am not sure.

Not specifically used SNMP for Artist, but regularly use SNMP to monitor other network devices on larger shows (UPSes, switches, APs, Routers, etc...).

One way to probe its functionality easily would be to have something like PRTG scan it and auto-generate sensors based on available data. This is often easier than querying the device for available MIBs and drilling down manually

I received this note on SNMP as enabled in the Artist Matrix.

Hello Pete,

Director will not show Artist temperatures, but it will show alarms of too high temperature.

Basically SNMP will show the same alarms as the Director Alarms window.
Our SNMP Agent only supports v1 protocol.

Mit freundlichen Grüßen /
kind regards

So what is the point?  I suppose if you had a permanent install of Artist and rarely connected Director, SNMP monitoring could tell you when an error occurred.  For a live show user, what we really need is more info, like the actual temp in the frame.  Not going to happen.

Are they saying that their SNMPv1 agent doesn't provide this information, or that their monitoring software doesn't support that? I'm guessing it's the later. It would be a fairly trivial task to script a custom SNMP monitoring program. I did this on Unix machines all the time, back in the 90s when SNMP was young.

Perl was a popular choice in scripting language. I preferred the TCL variants.

SNMP V1 in Artist has not specified quantitative temperatures.  The agent only has these variables:  Note the severity variable is a no 1-255 so it certainly could be a temp.  Customer support will not tell me what the units are.

The MIB file lists:

Version information about the ARTIST SNMP agent, in a human-readable format.

A component of the ARTIST SNMP agent version number.

type of IP address stored in mainIpAddr.

IP address of the ARTIST node to connect to,

Whether there is a redundant controller card installed in the ARTIST node.

type of IP address stored in redundantIpAddr.

IP address of the redundant controller card  to connect to if the main one fails

Table of alarms currently active in the ARTIST system.

An entry (conceptual row) in the alarmTable.

A unique value, greater than zero, for each alarm; that is, an index on the alarmTable.

alarm creation time.

alarm last update time.

alarm type.

A human-readable description of the alarm.

alarm severity.

alarm path.

number of nodes currently online.

total number of client cards currently online in all the nodes in the system

More info from Riedel:

value of severity, 0-255 just means it is one byte. How many severity levels of alarms does an Artist have from minor to fatal? 4? 5? That´s the 5th column in the alarms window.

As Thorsten Schwieder explained the temperature ist nothing you can read out with snmp,
in fact the Artist is not able to respond to snmp at all. The snmp agent connects to the frame as
another Director instance and is only able to read out exact the same information displayed as
in the alarms window within Director itself. This information is then retrievable via snmp from the
snmp agent. Temperature ist not monitorable in real time with the current software available.

We have been told that the system log, if turned on, will record the actual temp.  It has an entry for every little thing that artist does, sometimes 100 per second. So when you download the file it's huge and takes an hour or 2 to get.  Then searching.....

Well you see it's not real time.

If it's not instrumented in the Agent, you can't alarm on it through SNMP. Parsing the log file should be pretty simple. Look for the specific string for the temp log, and grab the next character string. You could display it in a small window for real-time-ish monitoring.

How about an external temperature sensor? I have had good success with the itwatchdogs Watchdog 100. This is a rack mounted device that has internal temperature and humidity sensors as well as some other inputs and alerts by email, email to SMS text, or SNMP.

http://www.itwatchdogs.com/climate-monitor-watchdog-100-p67.html

They have non-rackmount models as well as PoE devices depending on where you need to put them. Prices are pretty reasonable.

How about an external temperature sensor?

That is the way to go.  Riedel has equivocated more about severity.

Quote
the threshold to raise the high temperature alarm is about 61°C.
 
In this case it is not critical by sense of the unit might be likely to collapse or similar. (By the way our high temperature alarms only have “minor” state).
 
Our Artist installation guide says: Operating temperature of the system: -5°C ... +55°C, so 40°C are within this spec.

Of course you might still have luck with a still operational Artist system if this is put carelessly into a rack in full sunlight in Death Valley.
The higher the temperature the higher the risk that some central electronic parts might fail and become defective or cause a reset.
 
But we are talking about long term impacts that we want to avoid if the hardware is settled into too warm environment.
Warmer environment would mean that electrical components will definitively have shorter life range and our intention of implementing the alarms was to give a hint to customers about this circumstance.
 
But to be clear at this point from view of customer service:
 
We clearly recommend to use Artist in environments which is typical for technical units, so about 21°C.
