= INSTOOLS Data = When a slice is instrumented using the [wiki:Instrumentize INSTOOLS instrumentation scripts], INSTOOLS automatically begins collecting traffic measurement data for the slice. The following provides and overview of the types of data that are collected and made available by [wiki:INSTOOLSSummary INSTOOLS]. This information is presented to the user via the [wiki:INSTOOLSInterface INSTOOLS Live View] interface. == Tables == INSTOOLS shows the contents of a variety of configuration tables, routing tables, caches, etc. The following is a list of tables that are available on most network nodes: * ARP table * IP Address Table * Loaded Kernel Modules Table (module list obtained from "lsmod" command on Linux ) * Process Table (process list obatined from "top" command on Linux) * Routing Tables * Active TCP connections * Active UDP Listeners == Graphs == INSTOOLS is able to plot traffic graphics for nodes and links. In particular, the following graphs are generated automatically by INSTOOLS: * Node CPU Utilization Graph - ( CPU usage [user and system] v/s time) * Node Memory Utilization Graph - (Memory usage in KB v/s time) * Node Total Traffic Graph (bytes v/s time) * Node IMCP Traffic Graph (packets v/s time) * Node Total TCP traffic graph (packets v/s time) * Node Total UDP traffic graph (packets v/s time) * Node Total IP traffic graph (packets v/s time) * Link Interface Traffic (byte count v/s time) * Link Unicast Traffic (packet count v/s time) * (In case of links, there are two graphs, one for each interface on the link) * Netflow graphs are available for a variety of ports/protocols including: "169","255",ah,eigrp,esp,icmp,ipinip,normal,skip,tcp,udp,aim, bo2k, dc, dns, edonkey, ftp, gnutella, http, https, imap, irc, kazaa, nntp, pop3, real, smtp, ssh, telnet, == Example Graphs == [[Image(graph_cpu_u.png)]] [[Image(graph_ip_traffic.png)]] [[Image(graph_memory.png)]] [[Image(graph_traffic.png)]] [[Image(graph_udp.png)]] == Example Tables == [[Image(table_address.png)]] [[Image(table_arp.png)]] [[Image(table_udp.png)]]
