Q. Where can I download Plesk type themes for webmin Web hosting control panel?
A. Webmin is a system configuration tool for Unix-like systems. It has a web-based interface (GUI) desktop environment independent, for configuring some of the internals of the operating system. Webmin is largely based on Perl, and is running as its own process, and web server. It usually uses TCP port 10000 for communicating, and can be configured to use SSL if OpenSSL is installed.

Q. How to find out more information about MySQL server status?
A. The MySQL server maintains many status variables that provide information about its operation. You can see upto date variables lists and explanation of its usages online. For example you can connect to MySQL server and execute SHOW STATUS
$ mysql -u vivek -p
mysql> show status;
| Variable_name | Value |
| Aborted_clients | 0 |
| Aborted_connects | 4 |
| Binlog_cache_disk_use | 0 |
| Binlog_cache_use | 0 |
| Bytes_received | 208711192 |
| Bytes_sent | 2331972589 |
| Com_admin_commands | 1 |
| Com_alter_db | 0 |
| Com_alter_table | 0 |
| Threads_connected | 1 |
| Threads_created | 53 |
| Threads_running | 1 |
| Uptime | 143182 |
186 rows in set (0.00 sec)
However it takes some time to understand these variables. I recommend using mysqlreport which makes a friendly report of important status variables.
From the project home page:
It makes a friendly report of nearly every status value from SHOW STATUS. Unlike SHOW STATUS which simply dumps over 100 values to screen in one long list, mysqlreport interprets and formats the values and presents the basic values and many more inferred values in a human-readable format. Numerous example reports are available at the mysqlreport web page.
The benefit of mysqlreport is that it allows you to very quickly see a wide array of performance indicators for your MySQL server which would otherwise need to be calculated by hand from all the various SHOW STATUS values
How do I use mysqlreport?
First, download mysqlreport perl script:
$ wget http://hackmysql.com/scripts/mysqlreport
Now, execute mysqlreport
$ ./mysqlreport --user vivek --host localhost --port 3306 --socket /var/lib/mysql/mysql.sock --passwordOutput:
Password for database user vivek:
