FOG Multicast Not starting anymore

lebrun78 · Fog Version: Fog 1.5.10 Server OS: AlmaLinux release 8.8

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 ?

@lebrun78 I think port 9000 is php-fpm listening port. Apache talks to the php engine over the loopback adapter (127.0.0.1). Can you check to see if php-fpm is running ps aux| grep php

I think if php-fpm is not running the fog web ui should also be broken.

You might want to look into /var/log/apache2 and /var/log/php-fpm for the error logs to see if there is any helpful errors. Also in /opt/fog/logs there should be a multicast log too. See if they give any help with the problem.

Hello, I have cleaned the database:

mysql> DELETE FROM multicastSessions WHERE 1;
mysql> DELETE FROM multicastSessionsAssoc WHERE 1;
mysql> DELETE FROM tasks WHERE taskTypeID = 8;

And restarted the server, I had urgent deply to taunch, and the multicast worked…

I have a high cpu level for mysqld about 20%

in /var/log/php-fpm/www-error.log I have

Should I increase php memory allocation ?

in /var/log/httpd/error_log I have maybe too many connections !

@lebrun78 How many computers in your environment that has the fog client installed on it?

On the fog server log into mysql client tool with mysql -u root -p

Then run this command in the mysql client

SELECT TABLE_NAME,ENGINE
FROM information_schema.TABLES
WHERE TABLE_SCHEMA = 'fog' and ENGINE = 'MyISAM';

Does it return results that look like this?

If so I have a fix for your, but I also need your help first because we are looking at performance tuning the mysql database. I need to collect some info from a fog site that has over 100 target computers running FOG.

@george1421 said in FOG Multicast Not starting anymore:

SELECT TABLE_NAME,ENGINE
FROM information_schema.TABLES
WHERE TABLE_SCHEMA = ‘fog’ and ENGINE = ‘MyISAM’;

Hello
I have a result that look like your, but I get only 51 rows .

I have more than 300 computer deployed with Fog so I collect info that you need.

@lebrun78 Thank you for the feedback . Your install is suffering from having the database engine for the tables in ISAM format instead of INNODB. We can fix this no problem.

OK now my needs. I want to use your mysql database with many fog clients to record how many queries take long than 1 second to complete. With your slow database it probably will be all of them. I want to do a before and after test to see the improvements and then once we get the improvements the after scan will give us hints how to make the database go even faster.

The following commands will turn on global query logging (note it might even make your database slower so we will only let it run for 30 minutes).

Log into mysql database as root and run these commands.

SET GLOBAL slow_query_log = 'ON';
SET GLOBAL slow_query_log_file = '/var/log/mysql/slowquery.log';
SET GLOBAL log_queries_not_using_indexes = 'ON';
SET GLOBAL long_query_time = 1;
FLUSH LOGS;

Let this run for 30 minutes at the time of day where you would have the most computers on line and pinging the FOG server.

Then after 30 minutes log back into mysql and run this command to turn off logging.

SET GLOBAL slow_query_log = 'OFF';

The last part is to make a report of the log file and post it in this thread or via a file sharing site. From the linux command prompt run this command to make the report

mysqldumpslow -a /var/log/mysql/slowquery.log >/tmp/slowreport.txt

Download the /tmp/slowreport.txt from the FOG server and post it here, please.

@lebrun78 Thank you this information is very helpful. It will help us develop several indexes for the database that will speed up the responsiveness of the database. Just for my knowledge the time span was 30 minutes of data collection?

OK to work on your performance issue. We are going to use this thread as the background of the fix: https://forums.fogproject.org/topic/14254/high-cpu-usage

The first thing I need you to check is to see if your installation of mysql/mariadb has several default values that will cause us troubles during the upgrade. The upgrade itself is pretty quick.

In the mysql console run this command and post the results here: SELECT @@GLOBAL.sql_mode global, @@SESSION.sql_mode session

This query will respond with something that looks like this:

mysql> SELECT @@GLOBAL.sql_mode global, @@SESSION.sql_mode session;
+-------------------------------------------------------------------------------------------------------------------------------------------+-------------------------------------------------------------------------------------------------------------------------------------------+

1 row in set (0.01 sec)

Please post the text of the query because we may need to copy some text back into a new command.

george1421

@george1421 based on the previous query this is what we will need to change. But don’t do that until we check the server default parameters and make a backup first.

OK these two settings are going to cause us trouble.

ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,  >>NO_ZERO_IN_DATE,NO_ZERO_DATE<<  ,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION

We need to find the mysql settings file. Lets use this search string to see if we can find the right file.

grep -r -e "[mysqld]" /etc

We are looking for a file that has the mysqld section heading.

Just under that section heading we need to insert the corrected parameters.

[mysqld]
sql-mode=ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION

Once that config file has been updated restart the mysql database. If the database comes back online then we can proceed to the next steps. We are almost done.

@lebrun78 Great it looks like the db restarted after the service parameters update.

Access the mysql database and run these commands. They should complete without an error.

Finally run this query to make sure everything has been switched over to INNODB.

SELECT TABLE_NAME,ENGINE
FROM information_schema.TABLES
WHERE TABLE_SCHEMA = ‘fog’

All of the table should now use the INNODB db engine. You will not need to do anything else it should start working right away better. I would reboot the FOG server though just to ensure everything works OK after the reboot. Once that happens you should see lower CPU usage as well as mysql and php-fpm services levels should return to normal.

@lebrun78 Well I guess I get an D- on this test.

OK
on this one

ALTER 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.

@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.

george1421

@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.
