FOG Multicast Not starting anymore

Hello
Multicast does not start anymore
I didn’t change anything on the server configuration.
So I restarted the server.
I have a service that listens on port 9000 with a lot of lines (1193 lines)
I don’t know where I could have a look ?tcp 0 0 127.0.0.1:9000 127.0.0.1:50380 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:50736 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:52706 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:50388 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:52350 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:50758 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:52534 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:51140 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:52260 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:51100 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:51414 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:51394 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:50290 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:50498 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:52752 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:51030 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:52590 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:50418 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:52324 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:50416 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:51384 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:51654 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:51170 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:52756 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:52532 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:52476 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:51660 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:50622 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:50326 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:51458 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:52610 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:52666 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:51768 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:50894 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:51186 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:50364 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:51230 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:50704 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:50412 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:52370 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:50828 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:51060 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:50110 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:52928 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:50838 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:51298 TIME_WAIT - tcp 0 0 127.0.0.1:9000 127.0.0.1:50852 TIME_WAIT -[B]Fog Version: [/B] Fog 1.5.8

@lebrun78 I don’t have hard evidence but I have doubts about your server. You should not have full memory usage with 300 client computers (guess). So I’m wondering if you made changes to the php-fpm settings to solve another problem. (??).
Search the /etc directory for a file called www.conf. In there I want to know if you adjusted any of these values
pm.max_children = 50 pm.start_servers = 5 pm.min_spare_servers = 5 pm.max_spare_servers = 35or this value
php_admin_value[memory_limit] = 256MCan you tell us more about the hardware your FOG server is running on? (Manufacturer and model) What about your hard drives on your FOG server, is it a VM disk, raid disk array or a single sata disk? Are you running any other programs on the fog server other than FOG?
You can reduce some of the load on your fog server by changing the FOG Client check in time from 5 minutes (default) to 10 or 15 minutes. This will slow down the number of clients that check in per minute to give your FOG server a chance to keep up.

Geoges, should I use this topic as a reference ?

But I don’t think I’ve been answered yet on how many computers with the FOG Client installed and if the php-fpm settings have been tweaked from the FOG defaults.
Within the SQL query log there is a list of hosts. That has about 500 entries.
Also I am quoting @lebrun78 post in this same forum topic some days ago:
I have more than 300 computer deployed with Fog so I collect info that you need.

Right now I’m of the opinion the FOG server needs more ram since swap space is being used. But I don’t think I’ve been answered yet on how many computers with the FOG Client installed and if the php-fpm settings have been tweaked from the FOG defaults. If we are talking about over 2000 computers we need to do some testing.
lebrun78 was able to provide some pre-innodb database upgrade statistics where it looks like we can optimize the database searches with some smartly created indexes. I didn’t want to go into that until he system returned to a normal state.

Ok, good it’s not an update loop. That’s important to know. So we are back to what George was onto with switching to InnoDB. In theory this should enable heaps more clients to query information from the database in parallel than before. But somehow looks like this was not actually the bottleneck on your system.
There are several topics here in the forums discussing performance and load:

…@george1421 Do you think tweaking PHP-FPM paramaters will help any further?
It’s a lot of work for devs to simulate high loads with several hundreds of fog-client machines. So this depends on people like you to be as keen to dig into it.
Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

@lebrun78 I can imagine the php-fpm processes being under some heavy load some time after things were kind of offline because many clients try to check in again in a short time. But if things are fine this should “cool down” after an hour (even earlier but surely after that much time).
So if it’s still high load in php-fpm processes I suggest you also look at the Apache logs (see my signatur) and maybe even fog-client logs on machines (C:\fog.log). Post log information here so we can help interpret it.
-
@lebrun78 looking at
topscreen it looks like you are using quite a bit of RAM and even dipping into swap space. Did you increase the number of php-fpm workers or increase the per worker memory limit at one time. These changes would have been made to the php-fpm config file. -
@lebrun78 Well that didn’t seem to fix the issue. It should have, but you still have a long waiting list. How many client computers do you have in your network where the fog client is installed?

Il have allways too many time wait on port 9000
[root@fogus ~]# netstat -nat |grep 9000 |wc -l 855and php-fpm is allways high

@lebrun78 You might ask, why did I have you change the engine and how will that help with performance?
The simple answer is MyISAM uses table level locking when something is updated. INNODB engine uses row level locking on an update. Under table level locking when someone goes to update a table, that processing updating the a row causes all other processes to stop updating until the write is complete. Under row level locking, only the database row that is being changed is locked all other tables and rows are free to be updated by other processes. The table level locking of MyISAM will create a back log of processes waiting their turn to update the database.
You will see this backlog by higher than normal cpu percent on the mysql process and many (many) php-fpm processes waiting their turn to update the database.
-
@lebrun78 Excellent. I forgot that group was a keyword AND a table name. Good find to escape the table name.
And for the table engines good, that is exactly what we need.

@lebrun78 Well I guess I get an D- on this test.
OK
on this oneALTER TABLE groups ENGINE=InnoDB;There might be an artifact in there like a tab character because of the way I created the file. Try running that again like this:
ALTER TABLE groups ENGINE=InnoDB;In the case of this one:
mysql> SELECT TABLE_NAME,ENGINE FROM information_schema.TABLES WHERE TABLE_SCHEMA = fog; ERROR 1054 (42S22): Unknown column 'fog' in 'where clause'I think you are missing the single ticks around the fog value. It should look like this
SELECT TABLE_NAME,ENGINE FROM information_schema.TABLES WHERE TABLE_SCHEMA = 'fog'All this query does is prints out all of the tables in the fog database to confirm they are now all innodb format. All of the other tables converted correctly except the groups table. You should see a drop in cpu usage for by mysql and php-fpm already.
