The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This document describes the internal design and operational flow of the Prime Network monitoring graphs.
You can access the monitoring graphs from
https://<ip>:1311/graphs where '<ip>' is the hostname or IP address of your prime network gateway. For example,
The login user is admin and the password is the root GUI password.
The update.pl script gathers the individual performance data for each Autonomous Virtual Machine (AVM) into temporary hidden files in /tmp at 20-second intervals. These files are readable and provide the memory, cpu, log lines, and so on for each of the AVMs. They are the values from the AVM at the time when the file was created.
The script then copies these files to the gateway server. They place this data into the
~/.RemoteCommands/units/<IP>/graphs/<date/time>_graph_counters files on the gateway.
After the copy to the gateway, the unit deletes the files from /tmp.
The copy from the unit to the gateway is executed on the unit like this:
~/local/scripts/remote_copy.cmd $local_file $gateway_ip:$remote_file
The update.pl script processes the files that are generated by the gateway AVMs. The update_remote.pl script processes the files generated by the unit servers. These scripts read the files under .RemoteCommands once every minute. These files represent a single polling of unit data.
The script updates the *.rdd files in the ~/Main/scripts/monitoring/data directory. There is one file for each AVM in the system (ip_avm#.rdd). This .rdd file is a sliding window that contains one month of data from the .RemoteCommands files. It is compressed and not human-readable.
These two scripts also read all of the existing .rdd files in the data directory and create every possible individual graph that can be displayed.
It places these graphs into the ~/Main/scripts/monitoring/output directory. They have the format of <ip>_<graphType>_<timePeriod>.png. These files can be viewed in any picture viewer or displayed in a web page.
The individual web pages display various graphs that can be seen individually if you look in the
The graph.cgi and mcstats.cgi display the proper graphs based on user selections.
