On the reporting engine, and a new name - Kontrollbase
+0 Vote Up -0Vote Down

Update for all of those that are following the progress of Monolith. I’ve been busy this week coding the reporting engine - the code that analyses the hundreds of variables that are being collected - and I’m pleased to say that Perl was the correct choice for this application.Installation on the client servers will be a breeze, and relatively few non-standard modules are required for the server application.

I’ve been silently wondering for some time if the reporting engine equations should be part of a pluggable system (stored in the database) or if they should be hard coded. After writing up all of the equations, I’ve come to the conclusion that, for a quicker release, the equations and reporting engine will be hard-coded this time around for the default system alerts. Howeve -> user-defined alerts will be pluggable. Revisions ahead of 2.0 might feature pluggable main

Seeking volunteer test machines for Monolith

Monolith: MySQL server monitoring. I only have servers that run Redhat/Debian/Ubuntu Linux x86 and x86_64. I don’t have machines to test MySQL monitoring for the following OSes. Perhaps you would like to be a test candidate for the new version of Monolith? If so, let me know and you’ll be on the list, as well as get beta testing credit.

OSX Server: PPC and Intel

AIX

FreeBSD / OpenBSD / NetBSD

Windows Server

Solaris: Intel & Sparc

Linux servers that are NOT Intel based.

What this involves: testing the client script, perl modules, snmp stats, and other functions that may require a custom client script for that architecture.

Update: OSS MySQL Monitoring Solution
+0 Vote Up -0Vote Down

Progress on the Open Source enterprise grade MySQL monitoring system;  the schema for Monolith version 2 has been designed. Due to the many suggestions for features and the interest it has received I’ve put this on the front burner. That said, here is some more info on the next steps I’ll be taking.

  • Monitored servers will use a command line agent (called remotely) to pull information from both MySQL and the OS.
  • Historical information will include all values from global status and global variables, as well as CPU/Memory/IO/Disk usage.
  • Standard graphing functions - the ones in the list from the previous post - will gather information from various view tables that contain historical data that is collected from the agent script. User defined graphing will allow you to look at historical values over time for any of the various global status or global variable settings

+0 Vote Up -0Vote Down

What would you like to see in a free enterprise-grade monitoring system for your daily MySQL needs?I’m rewriting Monolith - MySQL DBA Console from the ground up. This will be version 2 and I would like to get some input from the global MySQL community.So far I am going with the following; comment with any improvements/additions.

  • Variable interval polling of server statistics
  • Over 50 different alerts (see list below)
  • Graphing of various server statistics (see list below)
  • Tuning recommendations with cnf file changes to apply to server
  • Change control documents for recommended performance/security tuning
  • Threshold based alerting with multiple alert groups: info,warn,critical
  • Sorting/ordering of servers via groups. ie: client -> dev,stage,prod
  • RSS feeds for each alert group
  • XML export with user defined fields for external

Parallel mysqldump backup script available. Testers wanted.
+0 Vote Up -0Vote Down

Large databases, long mysqldump times, long waits for globally locked tables. These problems basically never go away when you rely on mysqldump with –all-databases or a list of databases, as it dumps schemas serially. I’m not going to explain serial vs parallel processing here since that’s a larger topic. Suffice to say that in these days of multi-core / multi-cpu servers we only make use of one processor’s core when we serially export databases using mysqldump. So, I have a new script that attempts to alleviate those issues and now I need testers to provide feedback/improvements.

 

In order to keep some sanity when dealing with hundreds of database servers, the script takes care of the following:

  • low global locking time requirements: solved by parallel tasks / forked processes
  • backup file checking: with

    Comparison - Monolith vs. MySQL Enterprise Dashboard
    +0 Vote Up -0Vote Down

    I’m attempting this is be as unbiased as possible, since I write the Monolith application. This will hopefully help one decide between a free MySQL server monitoring system and paying for a per-server based licensed product. Both have strengths and weaknesses that should be pointed out before making a decision. You can infer the weaknesses based on the strengths below. That said, let’s just get into it.

    Strengths of each product over the other

    • runs mysql server backups remotely and reports on backup state execution
    • collects cnf files from each server during the talkback script execution for historical viewing
    • built on the LAMP stack, no need for tomcat/jboss
