Information on the Cisco Router Data Collection

The router inteface data collection is driven by a crontab entry in /usr/local/netdata/crontabs/cronlist.peleus*. It is performed once an hour. Since the list of active router interfaces is dynamic, it is fetched from CANDO at various times during the day and the data collection program uses this list /usr/local/netdata/sql.data/rtr.nodes* to know which routers to collect data from.

The analysis for the tabular reports and graphs for yesterday, weekly, and fortnightly are produced between 3 and 8 am daily.

In the analysis, certain data values which exceed thresholds are flagged as alerts, and are extracted for the Daily Summaries.

/usr/local/netdata/routers/src/arpdump

This script dumps the routers' arpcaches and checks for duplicate IP addresses being used on the network.

/usr/local/netdata/routers/src/cklog

This script continually looks for alerts produced by the routers and notifies certain users' of the alerts by displaying a message on their terminals.

/usr/local/netdata/routers/src/fetch.data

This script fetches statistical data (Collisions, Input Queue Drops, etc.) for each port on the routers.

/usr/local/netdata/routers/src/fetch.data.daily

This script fetches daily statistical data for each port on the routers.

/usr/local/netdata/routers/src/rinfo

This script extracts data from the router data collection and generates a tabular report.

/usr/local/netdata/routers/src/rlist

This script was designed to display long lines of router data files in a resonable fashion.

/usr/local/netdata/routers/src/rmccb.info

This script extracts data from the router data collection and generates a tabular report.

/usr/local/netdata/routers/src/rp

This script totals the statistics for each router for a specified period of time.

/usr/local/netdata/routers/src/rr

This script creates the daily summary report for the routers.

/usr/local/netdata/routers/src/rtr

This script uses the commands listed in rtr.cmds and retrieves the data genereated by those commands from rtr-cl.

/usr/local/netdata/routers/src/rtr2html

This script converts the dail router reports to html for World Wide Web display.

/usr/local/netdata/routers/src/rtrlog.daily

This script fetches the alert messages generated by the routers each day.

/usr/local/netdata/routers/src/rtrrpt

This script totals the statistics for each router for a specified period of time.

/usr/local/netdata/routers/src/rundailyreport

This script calls rtrrpt to create the daily summary report for the routers.
