LCDProc 0.5.4-dev

m4f1050

Here is my recent log of LCDproc after a fresh reboot of my Firebox, right now I have System Time and System Stats working.

EDIT: I had my WAN cable unplugged. I replaced my X500 with my X700 while I did this…

@stephenw10:

The more people running this and giving feedback the faster it's likely to be solved. So thanks. :)
If you are running it again try to SSH in. After you enter the password it appears to have frozen but if you wait long enough it will log in (several minutes). Then you can see what's running. E.g.

You should see one instance of each of those three programs running. If you have more then it has started or stopped incorrectly.

You can also run```
top -SH
LCDd should be consuming 1% or less cpu.

Steve

Thanks Steve but I've tried that and even after more than an hour I still cannot get the menu so I usually give up and do a power-cycle as that is the only way I've found to recover.
I would love to be able to confirm if there are multiple instances as well as memory usage and such but so far that is not an option.

I forgot to mention previously that someone had suggested that when the connection drops that all the packages are restarted so I disabled the gateway monitor but that made no difference.

The next time I get to watch it for a full day (next weekend?), I will keep an SSH session up running top and hopefully capture some useful information.

EDIT:
One more thing: The looking at the RRD graphs (processor, memory, & states), there is nothing indicating an increase in processes or utilization. Everything is "normal" and then just stops graphing until I reboot.

I turned LCDd on overnight and left my SSH sessions active running top -SH
This morning I have an unresponsive machine except the SSH sessions are still active. (Also, everyone was asleep so there was no usage from LAN to WAN.)

I killed the LCDd process after capturing the information below and load drops to less than .10 but I cannot restart it. If I use the webif it will generate the previously mentioned log entries and the same occurs starting it from the CLI.

Further confirmation of a problem. Thanks.
By the way pfSense uses circular logs so you have to use clog to tail them.

Well, today when I woke up and saw my Watchguard I noticed the "Thanks for using pfSense" and hung LCDd… I can restart it, but it would be nice for it not to crash. Will keep testing... All I did was add Interface (and on the dropdown kept WAN)

Hello everybody,
I just updated the package. The news are the following:

Fix the uptime screen
In the settings, "Enable LCDproc" becomes "Enable LCDproc at startup"
Added "After Install Info" message
Limited the client loop to three times. After three errors connecting to the LCDd service the client will end

I hope the 4th point will solve the problems for the Firebox boxes! Just wait for the 0.9 version of the package and update it…

Thanks to all for the feedbacks,
Michele

EDIT: With a feedback, please post the driver/port you're using, the values of the options of the service and the list of the screens active, thanks!!

power_matz

Hello,

can I leave the LED backlight on all the time? Is this implemented in this update?
Or will it come in a future version?

M.

stephenw10

@power_matz: The backlight control is part of the driver not the package so this won't have changed.

@mdima: Awesome work! ;D I can't wait to test it.

@power_matz:

We are currently focusing on fixing the issue of multiple instances of the server, as well as building the code for driving the LEDs. Once that is stable, we can revisit the user parameters.

Well the update didn't help for me… :(

Running clog of /var/log/system.log showed no entries related to the LCD processes.

However it DID continue to work properly this time although the screens changed about every 7 secs or so instead of 5 secs with the webif non-responsive and new SSH sessions not completing to connect. Existing SSH sessions continue just slowly as expected under the load.

For reference all my settings for the Firebox x700 are "default" with "2x20 columns" and the SDEC driver on /dev/lpt0. The only screens enabled are: Uptime, Load, States, Mbuf, & Interface Traffic (WAN).
GW monitoring is disabled.

EDIT: Forgot to add

like the new Uptime screen! Much cleaner.
in my set up, it seems to be failing after around 16-18 hours uptime and/or around 4-5am, not sure which yet, with no network activity occurring.

Hi Tix,
thanks for the info! I am now running my secondary machine with the same screens in order to test the "client" part of the package. If there is something wrong in the client for this screens I will find out soon. Of course I can only test the client because I use a different driver… but if the test goes OK it means some problem in LCDd 0.5.5 or the driver.

Thanks for apreciating! I will see tomorrow how my secondary machine is doing…

Ciao,

You think you can program more stuff on the LCDproc MENU?

Maybe stuff like webGUI restart, backup config, restore config, reboot system

Thanks! Doing an awesome job!

To all, I am using GWXepc for the Arm/Disarm LED to turn it green when pfSense comes up and red when it goes down.
What I did was edit the beep.sh and in "start" I added GWXepc -l green and in "stop" I added GWXepc -l red

:)

I've now been running 0.54 versions of LCDd and sdeclcd for 24hrs and am still experiencing the same LCDd CPU usage lock out. So I think we can rule out going to 0.55 as a problem.
Interestingly I was able to observe it happening this afternoon and it ramps up slowly as if it's looping around creating steadily more and more processes until it hits 100% cpu.

One way to test this would be to compile the old driver against 0.55 and run that. I don't have a suitable compile environment setup at the moment though.

Steve

mdima

Steve,
how many instances of the client were running at that time? Do you have any log that evidence problems or concurrent clients running in the same time?

Thanks,
Michele

stephenw10

Hmm, I'm not sure what you mean.
There were two distinct problems I experienced.
Firstly where multiple copies of the client ended up running. This happened immediately after either rebooting or restarting the service.
Secondly where LCDd ends up using 100% cpu. Just one client can be running when this happens.
I don't have much by way of logging. Can we increase the logging level in lcdd.conf?

Ok, but thanks to the last change the "second client" was stopped after 2 more attempts to connect, I guess.

Ok, that's awesome. At least we know that the issue is not related to multiple instances of the client running, which in any case should not give any problem (since LCDd is made to support different clients in the same time), but for sure it is not a "resoruce leak" because of the PHP client bothering the system…

Thanks,
Michele

stephenw10

Yes I agree two distinct situations.
The first should have been solved by your recent update, thanks!
Though as you say LCDd can support multiple clients. Interesting though that this doesn't arise with any other driver even though it should not happen.

@mdima:

@jpsb:

I just use the HD44780 in the driver list, and by connecting the display, the system log shows "LCD2USB device found"
The display is a little slow, and works best by refresh frequency on 5 or 10 sec.

Hi JPSB,
mmhhh… seems strange... how many screens you have active? Did you have the same problem also with the previous version?

Thanks,
Michele

Hi Michele

Yes I had the same problem with last version.
I only have "Interface Traffic" and "Load" running.
But the new version with options to change contrast, etc. makes the display is running perfectly.
I have not had any luck getting the new driver "hd44780 Fast" to run.
But as I said, it runs perfectly with the other changes.
So once again, many thanks for a fantastic job.

See my youtube video of the display:

Hi I having problem with the display running on the alix2d13 hardware.
After about 12 hours, the CPU load runs at 100%, and Pfsense freezer.
I have tried with multiple modules loaded but it makes no difference.

What if we roll back to 0.5.4 (now the package works with 0.5.5)??
