I wrote a script to report individual interface values, and then edited the ganglia PHP to display a network report (along with load, CPU, memory, etc.) that showed each interface in a different color. The script is at http://cryptio.net/~ben/ganglia/network_gmetric.sh I think I only modified conf.php and graph.php. I added the following lines to conf.php -=-=-=-=-=-=-=-=-=----8<----=-=--=-=-=-=-=-=----8<-----=-=-=-=-=-- # # Colors for the split network report graph # $total_rx_color = "FF0000"; $total_tx_color = "0000FF"; $eth0_rx_color = "333333"; $eth0_tx_color = "00FF00"; $eth1_rx_color = "FF00FF"; $eth1_tx_color = "00FFFF"; -=-=-=-=-=-=-=-=-=----8<----=-=--=-=-=-=-=-=----8<-----=-=-=-=-=-- I made the following changes to graph.php -=-=-=-=-=-=-=-=-=----8<----=-=--=-=-=-=-=-=----8<-----=-=-=-=-=-- [EMAIL PROTECTED]:/var/www/html/ganglia$ diff -c graph.php.orig graph.php *** graph.php.orig 2005-05-09 11:27:45.000000000 -0700 --- graph.php 2005-09-27 16:20:26.000000000 -0700 *************** *** 18,25 **** # Assumes we have a $start variable (set in get_context.php). if ($size == "small") { ! $height = 40; ! $width = 130; } else if ($size == "medium") { --- 18,25 ---- # Assumes we have a $start variable (set in get_context.php). if ($size == "small") { ! $height = 60; ! $width = 200; } else if ($size == "medium") { *************** *** 176,181 **** --- 176,215 ---- ."LINE2:'bytes_in'#$mem_cached_color:'In' " ."LINE2:'bytes_out'#$mem_used_color:'Out' "; } + else if ($graph == "split_network_report") + { + $style = "Split Network"; + + $lower_limit = "--lower-limit 0 --rigid"; + $extras = "--base 1024"; + $vertical_label = "--vertical-label 'Bytes/sec'"; + + $series = "DEF:'total_tx'='${rrd_dir}/network_tx.rrd':'sum':AVERAGE " + ."DEF:'total_rx'='${rrd_dir}/network_rx.rrd':'sum':AVERAGE " + ."DEF:'eth0_rx'='${rrd_dir}/eth0_rx.rrd':'sum':AVERAGE " + ."DEF:'eth0_tx'='${rrd_dir}/eth0_tx.rrd':'sum':AVERAGE " + ."DEF:'eth1_rx'='${rrd_dir}/eth1_rx.rrd':'sum':AVERAGE " + ."DEF:'eth1_tx'='${rrd_dir}/eth1_tx.rrd':'sum':AVERAGE " + ."LINE3:'total_tx'#$total_tx_color:'Total TX' " + ."LINE3:'total_rx'#$total_rx_color:'Total RX' " + ."LINE2:'eth0_tx'#$eth0_tx_color:'Eth0 TX' " + ."LINE2:'eth0_rx'#$eth0_rx_color:'Eth0 RX' " + ."LINE2:'eth1_tx'#$eth1_tx_color:'Eth1 TX' " + ."LINE2:'eth1_rx'#$eth1_rx_color:'Eth1 RX' "; + } + else if ($graph == "disk_report") + { + $style = "Disk"; + + $lower_limit = "--lower-limit 0 --rigid"; + $extras = "--base 1024"; + $vertical_label = "--vertical-label 'Blocks/sec'"; + + $series = "DEF:'disk_writes'='${rrd_dir}/disk_writes.rrd':'sum':AVERAGE " + ."DEF:'disk_reads'='${rrd_dir}/disk_reads.rrd':'sum':AVERAGE " + ."LINE2:'disk_writes'#$mem_cached_color:'Write' " + ."LINE2:'disk_reads'#$mem_used_color:'Read' "; + } else if ($graph == "packet_report") { $style = "Packets"; -=-=-=-=-=-=-=-=-=----8<----=-=--=-=-=-=-=-=----8<-----=-=-=-=-=-- -ben -- Ben Hartshorne email: [EMAIL PROTECTED] http://ben.hartshorne.net
