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:
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.
rrddd /OverTime/data/ = The directory that OverTime will create sysName directories in that in turn will house the RRD databases.
devcfgdir /OverTime/cfgs/ = The directory that OverTime will create sysName.mst within.
dnsfile /OverTime/cfgs/ot.csv = The file that OverTime uses to simplify the creation of index.html.
roothtml index.html = The name of the HTML file that houses the list of devices being monitored by OverTime.
webdir C:\InetPub\wwwroot\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.
sample_time 300 = This is the default sample time in seconds that will be used for the creation of any new I/O based RRDs.
If the parameter is omitted, 300 (5 minutes) is assumed (This is user configurable for NEW RRDs).
pt_cmds PingTime- = The beginning of a file name that will hold the PingTime commands for a specific frequency.
I.E. PingTime-300 holds the 5 minute collection commands for PingTime.
pt_cgi C:\InetPub\cgi-bin\pingtime.exe = 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 ?? 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.
When set to 1, all instances are displayed on the 1 graph.
AvgMinMax 7=Creates RRD files that store Averages, Minimum and Maximum values.
It is the sum of 4 for Averages, 2 for Minimums and 1 for Maximums.
IgnoreErrors 0 = try to collect IO errors if the interfaces supports error collections. 1= do not try, always ignore errors even if available.
PrimaryDataPts 360=This is the total number of actual data values observed that will be stored in the RRDTool database.
Collectors 10= Number of threads used by the SNMP collection service. Maximum of 100, default of 10. The more threads you use the more load is placed on the server and network traffic but collections are performed in less time. Mostly the threads are waiting for responses so having more is usually fine.
