HP Capacity Advisor 7.2 User Guide

And it includes this description:
Check the comment of this event to see why the Linux agentless data
collection output is invalid. If the "Complete output" is empty, SSH
command execution likely timed out. Verify SSHD is working correctly
on this node.
And the Comments field contains:
Error parsing the output of the command "date +%s"; field "export:
Command not found." was expected to be an integer. Complete output is:
export: Command not found.
Suggested action: Access the managed node with HP SIM credentials on the command line. Change
the default shell for the HP SIM access user to bash.
Other possibilities
For suspected WMI issues on Microsoft Windows nodes (applies to agentless collection on Windows
and virtual machine management/Hyper-V data collection), if nothing else works, try running the
following command on the managed system to re-register WMI performance classes that may have
become unregistered, causing data collection errors:
wmiadap /f
For agentless collection on Linux, make sure that SSH (sshd) is running on the managed system.
Data may appear to be old when it is not
When time or time zone on a managed node is set incorrectly (that is, it is not synchronized with
the clock time on the CMS), the user may collect data and see only old dates for data collected.
Suggested action: You must complete the following tasks (the process is different for each operating
system):
1. Correct the time or time zone on your managed node.
2. Stop and restart the Utilization Provider daemon where the UP is in use.
Brief instructions for these tasks are provided here.
Setting the time or time zone
On an HP-UX or Linux managed node, use the date(1) command to set the correct time. On an
HP-UX system, the source of the time zone varies depending on the local configuration. See the
setting for the TZ variable in the files /etc/profile or /etc/TIMEZONE or the file /etc/
defaults/tz, if the TZ variable is not set. (For more information, see the manual pages for
ctime(3C) and environ(5). On SuSE Linux, see the file /etc/sysconf/clock. For other
versions of Linux, consult the operating system documentation.
On Microsoft Windows, right-click on the time displayed at the right end of the task bar and select
Adjust Data/Time. Select the Time Zone tab on the dialog box and select the correct time zone
from the drop-down list at the top. Click OK to close the dialog box and use the new time zone.
Stopping and restarting the Utilization Provider daemon
On HP-UX, use the following command:
kill `ps -ef | grep utild | grep -v grep | awk '{ print $2 }'`
On Windows 2003 Server: Start→Manage Your Server→Tools and Updates→Administrative
Tools→Services. Look for HP UtilProvider Data Collector in the Name column. Right click on the
row and select Stop. Wait for it to stop and then right-click on it again and select Start. Close the
Services window, the Administrative Tools window and the Manage Your Server window.
