The default Uptime Infrastructure Monitor error logging level is ALL messages. This can cause a large number of messages to be registered in the phperror.log file. Some example messages are:
[Fri Sep 29 17:25:17 2006] [error] [client 10.1.1.125] File does not exist: /opt/uptime4/GUI/images/reports.gif, referer: http://host/footer.php
[Fri Sep 29 17:25:17 2006] [error] [client 10.1.1.125] File does not exist: /opt/uptime4/GUI/images/globalscan.gif, referer: http:// host/footer.php
These messages have no direct impact on Uptime Infrastructure Monitor performance or functionality and should therefore not be a cause for concern. To remove these messages, disable logging of PHP warnings in Apache by following these steps:
Edit the <uptime_dir>/apache/php/php.ini file.
Modify the line from error_reporting = E_ALL to error_reporting = E_ERROR.
Delete the phperror.log file and restart the Uptime Infrastructure Monitor Web Server or uptime_httpd service (depending on your platform).
