Enhance SNMP-Binding (Out-Binding) #107

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
1. Feature Description
It would be great if openhab could poll values via snmp from other devices.
Instead of getting snmp-traps.

2. Example Use Case
Gettings temperature values from an OW-SERVER-ENET via SNMP 
(http://www.embeddeddatasystems.com/OW-SERVER-1-Wire-to-Ethernet-Server-Revision
-2_p_152.html)

Or reading values for cpu_load, hdd_temp, free_ram, ... from a server.

the underlying snmp4j-lib does support sending requests:

I just created a separate feature request for the OW-SERVER-binding.
https://code.google.com/p/openhab/issues/detail?id=381

But I think the snmpget/snmpset binding should be more important, because it is 
a widespread standard.

I have this coded and working - needs more testing, but should be available 
soon...
I'm not sure if the OW-SERVER will work though since I'm not sure if the OID 
will remain constant (I have a OW-SERVER so will try and work this out).

Great news!!
I am looking forward to help testing. ;)

Regarding the OW-SERVER:
You are right.
The IDs can change witch each reboot. :(

But it is good to know there is somebody with an OW-SERVER and 
java-developing-skills out there.
It keeps my hopes up. ;D

I should say that I'm a complete noob with openHAB and I'm using this as a 
learning exercise to learn bindings while giving my openHAB install some items 
to play with.

Before I release anything, I should say what I've implemented. This issue 
requests a "OUT Binding". I've implemented this as an IN binding. I could be 
wrong (I'm new to OH) but I think this should be incoming - outgoing would be 
if you wanted to control an SNMP OID.

The implementation is therefore -:
{ snmp="<192.168.2.253:public:.1.3.6.1.2.1.2.2.1.10.10:10000" }

Parameters are -:
*Address
*Community
*OID
*Refresh period

Existing SNMP items would need to be changed to the above format. I thought 
about keeping the existing format, but it seemed a kludge. If you only wanted 
traps, then you set the refresh period to 0.

I may still change the above slightly, and if anyone has any comments, then 
fire away.

This is cool, thanks for working on it! I too am an OpenHAB noob, but being
able to tie network status to OH is great. I am slowly using more and more
SNMP at my place.

GoogleCodeExporter commented 9 years ago 
Of cause the binding I requested was meant to be an "In-Binding".
I must have confused it, because the SNMP-Traps (wich are already supported) 
are "incomming" and I want to send SNMP-request "out" to the device. :)
Maybe someone can change the subject.

But I think in the long term we need an "Out-Binding" (snmpset) as well.

Maybe you can consider this be changing "{ snmp="<192." to "{ snmpget="<192.".
When someone enhances the binding it is easier to implment the out-binding as 
"snmpset".

I had considered SNMP SET, but not enough to implement it since I don't 
currently have a use case for it (yet).

My concept for the binding was -:
snmp="<192.168.2.253:public:.1.3.6.1.2.1.2.2.1.10.10:10000" for an SNMP GET
snmp="<192.168.2.253:public:.1.3.6.1.2.1.2.2.1.10.10:0" for an SNMP TRAP
snmp=">192.168.2.253:something more here" for an SNMP SET

I hadn't worked out the SET part yet, but I don't think we need an extra 
snmpget (and I don't think the binding system allows more than 1 name within a 
single binding) - just change the direction indicator.

Attached is a test version of the updated plugin. Note that this probably only 
works with v1.3 of OpenHAB.
Bindings are as per my previous note -:
snmp="<192.168.2.253:public:.1.3.6.1.2.1.2.2.1.10.10:10000" for an SNMP GET
snmp="<192.168.2.253:public:.1.3.6.1.2.1.2.2.1.10.10:0" for an SNMP TRAP

The configuration in the openhab.cfg file is still the same, and this is still 
used for registing the community for traps (which may need to be updated!). You 
do need to have something in the openhab.cfg file though in order for the 
binding to be run.

Please let me know if there's any problems - especially with TRAPs since my 
devices don't send them. I have tested traps, and it seems to work ok, but as I 
don't have any devices that send traps, I've had to use a program to manually 
send the them. This works, but I'd like to be sure that it still works 
"properly".

One thing that may need to be added is a check of the incoming address. 
Currently the check is on the OID, but I suspect that if multiple devices send 
the same OID, this would cause a problem resolving the item.

There's an exception thrown the first time the item is updated. I think I know 
why this is (I'd made an assumption that updated gets called before execute, 
but that's not the case here as the listening log entry is after the update 
entry!). I'll fix this.

However, I don't think that this should cause any problem with subsequent 
updates, and the exception is not thrown again. So, it looks to me as though 
there are simply no responses to the request. There should be a "PDU received" 
log entry as soon as the response comes in, so either the request isn't being 
sent, or the SNMP device isn't sending a response.

I'll fix the exception, add a bit more logging and provide an update.

Hey Guys,

Just wanted to say good work on the progress.  I have an SNMP semi-managed
switch which powers my phones.  It is a NetGear GS110TP 8 port PoE switch
for about 115 EUR... other bigger used managed PoE switches can be found on
eBay too... but they consume a lot of power and make a lot of noise.

One of my OpenHAB goals is to be able to check switch port power status, as
well as be able to turn on/off ports.  I am in fact already toggling power
just by using the Linux command snmpset.

I haven't played with the traps, but I guess OpenHAB could be informed when
the switch port power status changes.

I'm currently only using phones, but this same PoE concept would hold true
for PoE surveillance cameras and WiFi APs.  Not that PoE APs would be what
most people would have at home. ;-)

This again looks fine - yes - the SMPT should be SNMP :) (simple brain fade!).

Based on your binding string, I think you are using the OW-SERVER? I've not 
tried to talk to the OWSERVER with SNMP - can you provide me the full binding. 
You blanked out the community and ip address - I don't need the address 
obviously, but I can't seem to work out the community (at least I can't get the 
OWSERVER to respond). (please email me if you'd prefer - the bit missing at the 
front of my address is chris@cd.....

I can then try and test this with the OWSERVER - maybe there's an issue with 
SNMP version or something.

I am having some trouble with SNMP of my OW-Server. The service stops after a 
few hours and the device needs a reboot. But that's another problem.

So I am using an UPS from APC for this tests, because I now it works. :)
OID = 1.3.6.1.4.1.318.1.1.25.1.2.1.6.1.1
Object-Name = uioSensorStatusTemperatureDegC.1.1

The community string just contains a few characters. Nothing special.
But I cannot tell, because the device belongs to my employer. ;)

Number SNMP_T2 "APC UPS Temp [%.1f °C]" <temperature> (Temp) { 
snmp="<x.x.x.x:****:.1.3.6.1.4.1.318.1.1.25.1.2.1.6.1.1:10000" }

I will try some more this evening. :)

btw: The community strings for the OW-SERVER are public and private. I think 
you can't even change them.
But like I said. I have some trouble and need to reboot the device sometimes.

This issue is caused because the binding doesn't correlate the IP addresses.

The problem that christoph faces might have to do that he is using a "Number" 
item on a "String" result:

the result is "INTEGER: 22"

So I did some wiresharking. :)

It looks like the snmp-requests and responses are alright.

The OW-Server may be a little problem, because the returned value is an 
OctetString (like "28.1234") instead of an integer.

But the returned value of the UPS is an integer ("21").

Like SJo just found out the snmp-request is send tree times in my case .
I set the interval to 60 seconds, but the requests are send tree times each 
witch 2 seconds delay between them.

I can send you the wireshark-file if that helps, Chris.

Original comment by christop...@gmail.com on 2 Aug 2013 at 10:21

GoogleCodeExporter commented 9 years ago 
I had a look at the log SJo sent regarding the duplicates, and there doesn't 
seem to be anything strange with the binding. It's only showing a single 
request for each Item, but there are two responses.
I have retries set up - but there should be a 1500ms timout, and your responses 
are coming back in less time than this, so (theoretically!) this shouldn't be 
an impact, but maybe it's related? Of course, this probably doesn't explain why 
there would be 3 repeats.
I will make the timeout period, and the number of retries configurable values 
in openhab.cfg so we can turn this off to see if it changes things.

chrisop - I assume that your openhab is still not receiving the requests? If 
it's still not receiving the response in the binding then the wireshark log 
might be interesting.
Regarding the OWServer - I can't get mine to return SNMP requests. I tried 2 
SNMP programs last night without success. I might run up wireshark this morning 
and see what that shows.

Original comment by ch...@cd-jackson.com on 3 Aug 2013 at 7:34

GoogleCodeExporter commented 9 years ago 
Actually - retries was set to 2, so that would mean 3 requests in all, so that 
may explain the cause of the repeats, but the time between them from your logs 
doesn't convince me this is the issue. Anyway, retries now defaults to off, so 
let's see if that has an impact.

This version allows you to set the timeout, and the number of retries in the 
openhab.cfg file -:
# The SNMP retry timeout (in ms). Defaults to 1500.
#snmp:timeout=

# The SNMP number of retries. Defaults to 0.
#snmp:retries=0

I think I found the cause, now.
It's kind of an user error of myself. :(

I had the MIB browser "SnmpB" running all the time and closed it last night.
This program seems to "steal" all incoming snmp-responses.
A soon as I run the application again openHAB cannot get any snmp-responses.

Yes, I made some changes to fix a couple of issues in this area, but it's still 
an issue. I'm still "evaluating" OpenHAB here, so my config is still not right, 
but I also see this as an issue with other bindings at my end - is it only SNMP 
with your config? I tried debugging this this morning and found after the items 
is changed, the binding doesn't appear to be restarted (is the binding doesn't 
appear to be called from the core). I need to spend some more time on this, but 
the garden beckons.

Looking at your log, there are several "Loading file snmp.items" - some seem to 
work, others don't. Are the ones that work only after OH is started from fresh, 
or does it work some times, and not other?

Your binding is the only one that stopped working after items-reload so far.

I don't know why it worked for a short time in the previous log.
But every time I try to reproduce it, the binding stops after the items-reload.

Maybe Kai can help you with this issue.
Especially if this concerns other bindings, too.

Kai has confirmed that this is a general problem with 1.3, since it's happening 
with other bindings as well (and for other people).

I just tested the trap-function.
(The UPS-Webinterface has a button to send a test-trap)

The Log shows the trap arrives. ;)
18:23:53.889 DEBUG o.o.b.s.internal.SnmpBinding[:178]- Received PDU

= 1.3.6.1.4.1.318.0.636]]' from 'x.x.242.171/46762'

But to be honest I don't know, how to use this.

Is this item-config right?
  String SNMP_Trap1 "Trap: [%s]" <temperature>  { snmp="<x.x.242.171:public:.1.3.6.1.6.3.1.1.4.1.0:0" }

Aside from that I get these messages right after the trap comes in.

What does "Address inconsistent" mean?

btw: I think it would be better to display the ports with a colon 
(x.x.242.238:161)
Otherwise you get confused with the subnet-syntax (192.168.1.0/24).

Original comment by christop...@gmail.com on 3 Aug 2013 at 4:29

GoogleCodeExporter commented 9 years ago 
To be honest, I'm also not sure about traps. I've tested the functionality 
using a program I found on the web (SnmpTrapGen), but I wasn't really sure what 
the different parameters in the trap are and I don't have anything that 
generates a real trap. I'll have a read up about this and see if I can work out 
how it works.

>What does "Address inconsistent" mean?
It just means that it's checking the addresses as it loops through the items 
trying to find the right one with the right address and right id. It's a debug 
message while I was adding the address check and I'll remove it now.

>btw: I think it would be better to display the ports with a colon
I would agree, but apparently Java doesn't! I'm using a standard Java function 
to display the addresses. Java also expects the address to be passed in this 
format, so when I create the items in the binding, I also need to add the /161 
to the end of the IP addresses...

Ok.

So I guess this means, there is something wrong.
   18:23:53.892 DEBUG o.o.b.s.internal.SnmpBinding[:183]- Address inconsistent x.x.242.171/161 x.x.242.171/46762

This should match, but apparently doesn't.
"x.x.242.171/46762" seems to be the adress of the trap.
"/46762" is the source-port of the trap-package and veries everytime. (just 
tried with wireshark)
"/162" would be the default destination-port of a trap-package.

btw: Despite the issues I list here: GREAT WORK!! ;)

Original comment by christop...@gmail.com on 3 Aug 2013 at 6:54

GoogleCodeExporter commented 9 years ago 
Good point - there's nothing to say that traps have to come from port 161 or 
162. I'll change the address check to ignore the port - that ought to fix this 
one :)
It'll probably be tomorrow for the fixed version.

Original comment by ch...@cd-jackson.com on 3 Aug 2013 at 7:17

GoogleCodeExporter commented 9 years ago 
This version adds an address translation for TRAPs. It changes the port number 
from the incoming address to port 161 to allow it to pass the address checks 
when processing the PDU.
I've left the "address inconsistent" message in for now so we can check this is 
all working since I can only partly test change.

This should be fixed with my latest changeset!

Trap workes.
The trap is received and the OID "1.3.6.1.4.1.318.0.636" is stored as a string 
in the item.
This OID can be translated as "PowerNet-MIB::apcTestTrap".
Id the UPS loses the power input for example it would be another OID.

So you can create rules like:

  when
    Item SNMP_trap1 changed to '1.3.6.1.4.1.318.0.636'
  then 
    sendMail"Test-Trap received")

Feature request:
It would be really great if the binding could use MIBs to translate OIDs.
But that's just "nice to have". ;D

Perfect - thanks for testing this out.  I'll tidy a few things up (remove some 
debug messages) and push a final version.

I've also tested Kais latest changes, and the binding seems to start up ok now 
after the items have changed.

I think that the library to read the MIB is only available under a commercial 
license - I'll double check that, but I think that's the case so it's not 
possible to support that (unless I can find another library).

btw: Will this binding replace the existing snmp-binding? Will it be in v1.3?

In this case we need to think about users who might already using the previous 
binding.
Their configs might not work after updating to the new binding.

Otherwise we might want to rename this to avoid confusion about the two "snmp 
bindings".
