Overtime.cfg holds user defined system configuration information.


Overtime.cfg is a plain text file. Each line commences with a case sensitive keyword followed by a blank and then the value for this keyword.

The keywords, their defaults and meanings are shown here in the format:

keyword default=meaning


company None = This is usually the company or Organisation's name for the installation. This name is only used as part of the title in index.html. It can be any text.


cgidir cgi-bin = This is the directory that the web server knows about that houses the cgi programs for this system, including devdtl and devmst.


collectfile /usr/OverTime/collects = The name of the temporary file used by otadd and otdel to merge collections into snmpCol.conf.


rrddd /usr/OverTime/data/ = The directory that OverTime will create sysName directories in that in turn will house the RRD databases.


devcfgdir /usr/OverTime/cfgs/ = The directory that OverTime will create sysName.mst within.


dnsfile /usr/OverTime/cfgs/ot.csv = The file that OverTime uses to simplify the creation of index.html and for ottgts.


sys_out_file /usr/OverTime/sys_out.txt = A temporary file used internally.


ov_dbs /usr/OV/databases/snmpCollect/ = The location on the system where IBM NetView keeps the snmpCollected data.

roothtml index.html = The name of the HTML file that houses the list of devices being monitored by OverTime.


webdir /usr/OV/www/htdocs/OverTime/ = The directory path where the graphics directories will be created. This is from the operating systems perspective and not from the web server’s perspective.


websubdir /OverTime/ = This is the web servers’s perspective of the same location as webdir above.


graph_parms –z = This is the string to be passed to the RRD graph command for additional features.

h 400 –w 800 –z would change the size of the graphs to this height and width and only create the graphs if they are not current.

An understanding of RRD graph is needed to use this properly.

If the parameter is omitted, 300 (5 minutes) is assumed (This is user configurable for NEW RRDs).

I.E. PingTime-300 holds the 5 minute collection commands for PingTime.


pt_cgi /usr/OV/www/cgi-bin/pingtime = the fully qualified location and the name of the PingTime executable.


Indexbysysname 1=Determines what labels should be shown in the roothtml page.

1 indicates that sysNames should be used while a 0 indicates that NetView's selection names should be used.


groupall 1=display all the instances for a particular part of a MIB on the one graph or separate graphs.

When set to 0, each instance is displayed on a separate graph.
