+# mysql
+
+> THIS MODULE IS OBSOLETE.
+> USE [THE PYTHON ONE](../../python.d.plugin/mysql) - IT SUPPORTS MULTIPLE JOBS AND IT IS MORE EFFICIENT
+
+The plugin will monitor one or more mysql servers
+
+It will produce the following charts:
+
+1. **Bandwidth** in kbps
+ * in
+ * out
+
+2. **Queries** in queries/sec
+ * queries
+ * questions
+ * slow queries
+
+3. **Operations** in operations/sec
+ * opened tables
+ * flush
+ * commit
+ * delete
+ * prepare
+ * read first
+ * read key
+ * read next
+ * read prev
+ * read random
+ * read random next
+ * rollback
+ * save point
+ * update
+ * write
+
+4. **Table Locks** in locks/sec
+ * immediate
+ * waited
+
+5. **Select Issues** in issues/sec
+ * full join
+ * full range join
+ * range
+ * range check
+ * scan
+
+6. **Sort Issues** in issues/sec
+ * merge passes
+ * range
+ * scan
+
+### configuration
+
+You can configure many database servers, like this:
+
+You can provide, per server, the following:
+
+1. a name, anything you like, but keep it short
+2. the mysql command to connect to the server
+3. the mysql command line options to be used for connecting to the server
+
+Here is an example for 2 servers:
+
+```sh
+mysql_opts[server1]="-h server1.example.com"
+mysql_opts[server2]="-h server2.example.com --connect_timeout 2"
+```
+
+The above will use the `mysql` command found in the system path.
+You can also provide a custom mysql command per server, like this:
+
+```sh
+mysql_cmds[server2]="/opt/mysql/bin/mysql"
+```
+
+The above sets the mysql command only for server2. server1 will use the system default.
+
+If no configuration is given, the plugin will attempt to connect to mysql server at localhost.
