Python Plugin: Network Pinger (Native ICMP) Topic is solved

[gerardwr]

@gerardwr,

You can change the name of the device in Domoticz to anything you want using the normal "Edit" button in the "Switches" tab. The plugin sets a default name but does not rely on it remaining the same.

Yes I understand.

But suppose I would like to Ping 20 devices, you would have to edit the names of these devices individually. Defining the relation between name and IP in 1 place sounded appealing to me.

[Dnpwwo]

November 29th, 2017, version 3.0.1:

• Devices are created in Domoticz the first time the plugin runs, one to show if the device is found and one to show the response time.
• Devices that are not found are optionally shown with a red banner in the devices tab (if configured to do so)
• New version handles DNS names where the IP addresses changes (e.g www.google.com) without creating new devices in Domoticz

Users of the previous version should 'Delete' then 'Add' the plugin via the Hardware page.
Requires recent beta for the response time devices to be updated.

November 29th, 2017, version 3.0.1:

Just installed the updated plugin, works excellent!

Defined 3 addresses to ping in setting up, and for every address a "switch" and a "utility" is created automagically.

For each "utility" sensor a graph is made by Domoticz, picture below after 6+ hours.

Just as I wanted, well done, I'm happy

Hi,

I'm getting errors on the last version (3.01):

2017-12-01 12:18:17.675 Error: (Pinger) 'onHeartbeat' failed 'IndexError':'list index out of range'.
2017-12-01 12:18:17.675 Error: (Pinger) ----> Line 181 in /home/pi/domoticz/plugins/pinger/plugin.py, function onHeartbeat
2017-12-01 12:18:17.675 Error: (Pinger) ----> Line 157 in /home/pi/domoticz/plugins/pinger/plugin.py, function onHeartbeat

Any idea what could be wrong?

Regards, Rob

@schulpr,

Yes I do have an idea. I have been testing the plugin with multiple addresses lately and broke it for when only a single address is specified (which I'm guessing you have)

I've pushed an update to the Pinger example. Version 3.0.3 is here: https://github.com/domoticz/domoticz/bl ... /Pinger.py

[schulpr]

Hi Dnpwwo,

Thank you for the update, the script does work now but I still get an (different) error:

" 2017-12-02 08:27:45.743 Error: (Pinger) Transport not initialized, write directive to '192.168.2.12' ignored. Connectionless transport should be Listening."

I was indeed testing with only one IP-address. I'm trying different plugins to see which one of them fits best for my needs. I like this one because it's easy to install en managed within Domoticz. There is another one (Ultimate Wifi and Bluetooth Presence Detection) that also pings the bluetooth mac-address but this is another type of script.

So I was wondering if it is possible to ping the bluetooth device also in a Python script. (Combine the best of both worlds sort of speak .

Thanks for all your work in the Domoticz community. A lot of people are doing a great job here so people with less knowledge can benefit from this.

Kind regards, Rob

Yes, I've got this error too, exactly ON the hour, but not EVERY hour. Error log says

Code: Select all

no more this error till 22:45

In addition my error log contains this error EVERY hour

+1 Excellent work!

Despite the errors the plugin works fine !

I cannot get it to work, also not with the latest version of the plugin

I'm running Domoticz Version: 3.8337 on a Raspberry Pi 3 with Raspbian Jessie.

The python plugin subsystem seems to be working. Buienradar plugin and NUT UPS plugin are working without any problems.

[Dnpwwo]

@bizziebis,

ICMP and timed out devices are new features, you will need to be on a very recent beta. I'm on 3.8746

[bizziebis]

Thanks, I was to quick with trying and not reading first.. I'm on V3.8775 now and it's working great.

[bizziebis]

I noticed that this plugin was the root cause of my memory leak which I also mentioned in the Bug forum. Every hour it will take 0,6MB of memory which will result in almost 20MB memory increase of the Domoticz process each day.

Does anyone else have this problem too?

[Velly]

Confirm memory leak

+ getting thessev errors:

[Dnpwwo]

@Velly,

Can you have a look at the plugin.py and make sure you are running version 3.x.x?

I've looked at the code for 3.0.0 on github and can't see how you can get an error at line 149 without getting one at 148 first (which you don't)

[Velly]

@Dpnwwo

<plugin key="ICMP" name="Pinger (ICMP)" author="dnpwwo" version="3.0.3">

[Dnpwwo]

@Velly,

Can you try the version here: https://github.com/dnpwwo/Domoticz-Pinger-Plugin and let me know

That is the one I run successfully. Looks like I need to update the example version that ships with Domoticz

[Velly]

@Dnpwwo

Still same:
2018-02-14 19:22:23.264 Error: (Pinger) 'onHeartbeat' failed 'KeyError'.

NB: however Lines are changed - I did not compare by myself yet with previous plugin version.

I have about 8-10 python plugins working fine: - the second giving same looking errors is PiMonitor:
2018-02-14 19:21:53.663 Error: (PiMonitor) 'onStart' failed 'KeyError'.

I am on Jessie pi3 python 3.4

[Dnpwwo]

@Velly,

Line 148 makes more sense and I think I understand the problem but I can't understand why I never see it because I think I should as well.

Anyway, I pushed a new version to github that has better handling for the Options dictionary and should resolve this.

Could you pls take a look onto? - my knowledges in python are near zero level..

Thanks!

Hello,

I still have this trouble after updating Python and Domoticz.

What can I do to fix that ?

Thanks !
