Sending an HTTP Request

cafri · June 17, 2019, 5:42am

I am already familiar with everything you wrote (with regards to rules, and thanks to this thread, also with regards to timers).

I don’t use any Thread::sleep, all my sendHTTP* calls were within createTimer to prevent rules hanging, and apart of this my rules don’t use any timers (I do have 16 cron-based rules and 3 astro-based rules, but they are all well spread along the day).

I am not familiar, though, with the OS, how it should behave, and how to analyze the usage of resources, and making sure it works as it should, or I should look into specific areas and analyze them.

As @rlkoshak wrote,

I am looking for what causes the number of threads growing on my system, and whether this is a "temporary"grow (and threads get released over time) or it is a “constant” grow.

If it helps, my setup is using openhabian over a RPi 3B+ with the following bindings:

Astro (only 3 very short rules are triggered by the astro binding)
Expire (~30 items using it)
HarmonyHub
Xiaomi Mi (2 nodes connected to it)
Network (pinging 4 iPhones)
Samsung Tv (polling every 1 second)
openHAB Weather (polling every 2 minutes)
YamahaReceiver (polling every 10 seconds)
ZWave (~22 nodes connected to it)

Also using:

openHAB Cloud connector
Google Calendar connector
Mapdb for RestoreOnStartup
Influxdb for some other items (installed grafana as well, but didn’t “play” with it too much, yet)

Here is a the full bundle list:

Also, when I check the list of shell threads, it seems that there are many HttpClient threads - is this normal?

There is another way to achieve a similar result, that is by using the ipcamera binding and the create gif feature. I have been considering adding the ability to output an mp4 file instead of a gif.

The way it works is simple.

Use a rule to turn on the create gif switch when your door is opened.
When the file is created the binding turns the switch off and this can trigger a rule to send the email.
No timers or sleep needed as the binding handles this for you.

I am sending a still image easily using Telegram:

sendTelegramPhoto("bot1", "http://192.168.1.222/snapshot.cgi", "Door Opened when Kids home alone")

It would be great if the IP Camera Binding could send an email with a 15 seconds MP4 file.

The threads you listed make up all the rest of OH. Almost all of them are created and used by the core of OH and the bindings. You have no control over them.

I have no idea.

Maybe. It depends on how they are implemented. If thread pools are being used then there is a fixed number of threads that get reused. Otherwise it is the job of what ever part of the code that created the thread to release it when it’s done.

You would need to hook a profiler up to a running OH instance and be familiar with the code to understand what is creating Threads under what circumstances.

Thanks for the information.

cafri:

On June 13th at 10:45 it was 287
On June 13th at 15:12 it was 301
On June 13th at 16:48 it was 291
On June 13th at 23:33 it was 296
On June 14th at 08:35 it was 298
On June 14th at 23:03 it was 294
On June 15th at 23:48 it was 316
On June 16th at 21:46 it was 310

It seems like the number of threads continues to grow:

On June 16th at 22:21  it was 317
On June 17th at 08:15  it was 309
On June 18th at 19:49  it was 335
On June 19th at 00:21  it was 341
On June 19th at 10:16  it was 338

Are there any bindings / add-ons out of the ones I am using, that are known to cause this?
On the contrary - are there ones who are known for sure to NOT cause this?
(so I can try removing the remaining ones, one by one, and see which one causes this)

Or is it not that of an issue, as long as the CPU usage is not going high? (which currently seems like it is not going high)

matt1 · June 19, 2019, 11:10am

I believe telegram supports sending the animated gif so you can upgrade from a static picture to a moving one right away. If I was to add mp4 output i am not sure what abilities it would have, need to experiment when I get some spare time as to what is possible. Features like preroll before you ask to record may not be possible which is with the gif.

rlkoshak · June 19, 2019, 1:52pm

First of all, we don’t know that this is unusual and we don’t know that it is a problem. what does matter is the CPU utilization and RAM utilization.

There are no bindings that are known to leak threads nor is there any part of the core that is known to leak threads. That doesn’t mean there aren’t any, we just don’t know it if they do.
