Description:
MySQL Server 5.0.77
CentOS 5.3

# Customize this script to suit your system if necessary
# Shell function names and output format must be maintained

get_cpu_info = /usr/bin/uptime | wba_token(' ', 10)
get_mem_info = free | wba_filter(Mem:) | wba_token(' ', 3)
get_mem_total = free | wba_filter(Mem:) | wba_token(' ', 1)

These settings in MySQL Workbench cause SYSTEM HEALTH to continuously flash NO DATA and then come back with the stats.

Without these config settings, if they are removed, the SYSTEM HEALTH is fine.

How to repeat:
Add the get_cpu_info, get_mem_info, and get_mem_total

Suggested fix:
Do not know

I can not repeat the issue from windows 7 to oracle enterprise linux 5.5.

I see the same thing. DB is 5.0.89 running on RHEL. Client is 5.5.21 on Windows XP. It has happened on previous versions as well.

This problem cannot entirely be fixed. If your CPU load is high or the server connection slow so that no data comes in then WB shows that. This is on purpose to let you know if something is wrong. However, I increased the timeout from 5 to 15 seconds, so this does not show up too often, e.g. for short drops.

In the Administrator, system health displayed NO DATA.
