This is an old revision of the document!
A few new configuration files were placed in the <GANGLIA HOME>/ directory with the following content:
- maintenance_conf.php
<?php $maint_name = "maintenance"; $computer_metrics = array( "load", "mem", "cpu" ); $maint_rrdfile = array( "ROWS" => array( "rows" => "Total_Power.rrd", "rowscool" => "Calc_total_lcp_cooling_power.rrd", "clcpwaterflow" => "Calc_total_lcp_water_flow.rrd", "clcpairflow" => "Calc_row_lcp_water_flow.rrd" ), "ROW_2" => array( "rows" => "Total_Row_Power.rrd", "rowscool" => "Calc_row_lcp_cooling_power.rrd", "clcpwaterflow" => "Calc_row_lcp_water_flow.rrd", "rowsfan" => "Calc_row_lcp_fan_power.rrd", "clcpairflow" => "Calc_row_lcp_water_flow.rrd" ), "ROW_3" => array( "rows" => "Total_Row_Power.rrd", "rowscool" => "Calc_row_lcp_cooling_power.rrd", "clcpwaterflow" => "Calc_row_lcp_water_flow.rrd", "rowsfan" => "Calc_row_lcp_fan_power.rrd", "clcpairflow" => "Calc_row_lcp_water_flow.rrd" ), "ROW_4" => array( "rows" => "Total_Row_Power.rrd", "rowscool" => "Calc_row_lcp_cooling_power.rrd", "clcpwaterflow" => "Calc_row_lcp_water_flow.rrd", "rowsfan" => "Calc_row_lcp_fan_power.rrd", "clcpairflow" => "Calc_row_lcp_water_flow.rrd" ), "ROW_5" => array( "rows" => "Total_Row_Power.rrd", "rowscool" => "Calc_row_lcp_cooling_power.rrd", "clcpwaterflow" => "Calc_row_lcp_water_flow.rrd", "rowsfan" => "Calc_row_lcp_fan_power.rrd", "clcpairflow" => "Calc_row_lcp_water_flow.rrd" ), "ROW_6" => array( "rows" => "Total_Row_Power.rrd", "rowscool" => "Calc_row_lcp_cooling_power.rrd", "clcpwaterflow" => "Calc_row_lcp_water_flow.rrd", "rowsfan" => "Calc_row_lcp_fan_power.rrd", "clcpairflow" => "Calc_row_lcp_water_flow.rrd" ), "ROW_7" => array( "rows" => "Total_Row_Power.rrd", "rowscool" => "Calc_row_lcp_cooling_power.rrd", "clcpwaterflow" => "Calc_row_lcp_water_flow.rrd", "rowsfan" => "Calc_row_lcp_fan_power.rrd", "clcpairflow" => "Calc_row_lcp_water_flow.rrd" ), "ROW_8" => array( "rows" => "Total_Row_Power.rrd", "rowscool" => "Calc_row_lcp_cooling_power.rrd", "clcpwaterflow" => "Calc_row_lcp_water_flow.rrd", "rowsfan" => "Calc_row_lcp_fan_power.rrd", "clcpairflow" => "Calc_row_lcp_water_flow.rrd" ) ); $mgroup_metrics = array( "ROWS" => array( "rows", "rowscool", "clcpwaterflow", "pumptemp", "pumpdp" ), "ROW_6" => array( "rows", "rowscool", "clcpwaterflow", "clcpairflow", "rowsfan" ), "ROW_8" => array( "rows", "rowscool", "clcpwaterflow", "clcpairflow", "rowsfan" ), "ROW_7" => array( "rows", "rowscool", "clcpwaterflow", "clcpairflow", "rowsfan" ), "ROW_2" => array( "rows", "rowscool", "clcpwaterflow", "clcpairflow", "rowsfan" ), "ROW_4" => array( "rows", "rowscool", "clcpwaterflow", "clcpairflow", "rowsfan" ), "ROW_3" => array( "rows", "rowscool", "clcpwaterflow", "clcpairflow", "rowsfan" ), "ROW_5" => array( "rows", "rowscool", "clcpwaterflow", "clcpairflow", "rowsfan" ) ); function add_ipmi_metrics ($metrics, $rrddir){ $alledateien = scandir($rrddir); foreach ($alledateien as $datei) { // Ausgabeschleife if (substr_compare($datei,"ipmi",0,4) == 0){ $dateiinfo = pathinfo($rrddir."/".$datei); if($dateiinfo['extension'] == 'rrd'){ $metrics[$dateiinfo['filename']]['NAME'] = $dateiinfo['filename']; $metrics[$dateiinfo['filename']]['TYPE'] = 'float'; $metrics[$dateiinfo['filename']]['VAL'] = 0; $metrics[$dateiinfo['filename']]['SLOPE'] = 'both'; $metrics[$dateiinfo['filename']]['UNITS'] = 'a.u.'; $metrics[$dateiinfo['filename']]['GROUP'] = array("ipmi"); #error_log("add ipmii".$dateiinfo['filename']); } } }; return $metrics; } function add_ipmi_metrics_cview($hostname,$metrics,$rrddir){ $alledateien = scandir($rrddir); foreach ($alledateien as $datei) { // Ausgabeschleife if (substr_compare($datei,"ipmi",0,4) == 0){ $dateiinfo = pathinfo($rrddir."/".$datei); if($dateiinfo['extension'] == 'rrd'){ $metrics[$hostname][$dateiinfo['filename']]['NAME'] = $dateiinfo['filename']; $metrics[$hostname][$dateiinfo['filename']]['TYPE'] = 'float'; $metrics[$hostname][$dateiinfo['filename']]['VAL'] = 0; $metrics[$hostname][$dateiinfo['filename']]['SLOPE'] = 'both'; $metrics[$hostname][$dateiinfo['filename']]['UNITS'] = 'a.u.'; $metrics[$hostname][$dateiinfo['filename']]['GROUP'] = array("ipmi"); #error_log("add ipmii".$dateiinfo['filename']); } } }; return $metrics; } ?>

correction of the file metric.php in order to take new DS in to account:
...
$DSname="sum";
//# the actual graph...
if (substr_compare($metricname,"ipmi",0,4) == 0)
$DSname="ipmi";
$series = "DEF:'sum'='$rrd_dir/$metricname.rrd:$DSname':AVERAGE ";
$series .= "AREA:'sum'#$default_metric_color:'$subtitle_one'";
$series .= ":STACK: COMMENT:'$subtitle_two'";
...
in the file conf.php (in “/etc/ganglia/”) was inserted:
... include_once "./maintenance_conf.php"; ... # Set timezone date_default_timezone_set ( 'Europe/Berlin' ); ...
in the template file <GANGLIA HOME>/templates/default/meta_view.tpl the block “public” was changed:
... <!-- START BLOCK : public --> <TD ALIGN="LEFT" VALIGN="TOP"> <table cellspacing=1 cellpadding=1 width="100%" border=0> <tr><td>CPUs Total:</td><td align=left><B>{cpu_num}</B></td></tr> <tr><td width="80%">Hosts up:</td><td align=left><B>{num_nodes}</B></td></tr> <tr><td>Hosts down:</td><td align=left><B>{num_dead_nodes}</B></td></tr> <tr><td> </td></tr> <tr><td class=footer colspan=2>{cluster_load}</td></tr> <tr><td class=footer colspan=2>{localtime}</td></tr> </table> </TD> <TD ROWSPAN=2 ALIGN="CENTER" VALIGN=top> <table cellspacing=1 cellpadding=1 width=100% border=0> <!-- START BLOCK : graph_group --> <tr> <td> <!-- START BLOCK : metric_graphs --> <A HREF="{url}"> <IMG SRC="./graph.php?{graph_url}&g={metricname}_report&maint={m_name}&z=smedium&r={range}" ALT="{name} Load" BORDER="0"> </A> <!-- END BLOCK : metric_graphs --> </td> </tr> <!-- END BLOCK : graph_group --> </table> </TD> <!-- END BLOCK : public --> ...
in the file <GANGLIA HOME>/meta_view.php the following was changed:
- public cluster code is altered
... foreach ( $sorted_sources as $source => $val ) { ... if (!isset($private[$source]) or !$private[$source]) { $tpl->assign("alt_view", "<FONT SIZE=\"-2\">$alt_url</FONT>"); # Each block has a different namespace, so we need to redefine variables. $tpl->newBlock("public"); if ($localtime) $tpl->assign("localtime", "<font size=-1>Localtime:</font><br> " . date("Y-m-d H:i", $localtime) ); $tpl->assign("num_nodes", $grid[$source]["HOSTS_UP"] ); $tpl->assign("num_dead_nodes", $grid[$source]["HOSTS_DOWN"] ); if ($name == $maint_name){ foreach ($mgroup_metrics as $mname => &$mgrp) { $hostname = $mname; $tpl->newBlock("graph_group"); foreach ($mgrp as $g) { $tpl->newBlock("metric_graphs"); $tpl->assign("range", $range); $tpl->assign("name", $name ); $tpl->assign("m_name", $hostname ); $tpl->assign("url", "./graph.php?c=$name&r=$range&g=${g}_report&maint=${hostname}&z=large"); $tpl->assign("graph_url", $graph_url); $tpl->assign("metricname", $g); } } } else { if ($cluster_load) $tpl->assign("cluster_load", "<font size=-1>Avg Load (15, 5, 1m):</font>" ."<br> $cluster_load"); $tpl->assign("cpu_num", $m["cpu_num"]['SUM']); $tpl->newBlock("graph_group"); foreach ($computer_metrics as $g) { $tpl->newBlock("metric_graphs"); $tpl->assign("range", $range); $tpl->assign("name", $name ); $tpl->assign("url", $url); $tpl->assign("graph_url", $graph_url); $tpl->assign("metricname", $g); } } ...
in order to see the “last reported” metric by default in the “maintenance” overview the line 118 was changed:
if ($name == $maint_name) $tpl->assign("url", "./?c=$name&m=last_reported&r=$range"); else $tpl->assign("url", $url);
in order to list new IPMI metrics additionally in the cluster overview page the function start_cluster was changed to ganglia.php
- ganglia.php
... function start_cluster ($parser, $tagname, $attrs) { global $clustername, $rrds, $metrics, $cluster, $self, $grid, $hosts_up, $hosts_down; static $hostname; switch ($tagname) { case "GANGLIA_XML": preamble($attrs); break; case "GRID": $self = $attrs['NAME']; $grid = $attrs; break; case "CLUSTER": $cluster = $attrs; break; case "HOST": $hostname = $attrs['NAME']; if (host_alive($attrs, $cluster)) { isset($cluster['HOSTS_UP']) or $cluster['HOSTS_UP'] = 0; $cluster['HOSTS_UP']++; $hosts_up[$hostname] = $attrs; } else { isset($cluster['HOSTS_DOWN']) or $cluster['HOSTS_DOWN'] = 0; $cluster['HOSTS_DOWN']++; $hosts_down[$hostname] = $attrs; } # Pseudo metrics - add useful HOST attributes like gmond_started & last_reported to the metrics list: $metrics[$hostname]['gmond_started']['NAME'] = "GMOND_STARTED"; $metrics[$hostname]['gmond_started']['VAL'] = $attrs['GMOND_STARTED']; $metrics[$hostname]['gmond_started']['TYPE'] = "timestamp"; $metrics[$hostname]['last_reported']['NAME'] = "REPORTED"; $metrics[$hostname]['last_reported']['VAL'] = uptime($cluster['LOCALTIME'] - $attrs['REPORTED']); $metrics[$hostname]['last_reported']['TYPE'] = "string"; $metrics[$hostname]['ip_address']['NAME'] = "IP"; $metrics[$hostname]['ip_address']['VAL'] = $attrs['IP']; $metrics[$hostname]['ip_address']['TYPE'] = "string"; $metrics[$hostname]['location']['NAME'] = "LOCATION"; $metrics[$hostname]['location']['VAL'] = $attrs['LOCATION']; $metrics[$hostname]['location']['TYPE'] = "string"; /* Addition of IPMI metrics */ $rrddir = "$rrds/$clustername/$hostname"; $metrics=add_ipmi_metrics_cview($hostname,$metrics,$rrddir); #error_log("rrd= $rrddir"); break; case "METRIC": $metricname = $attrs['NAME']; $metrics[$hostname][$metricname] = $attrs; break; default: break; } } ...
in order to see the IPMI metrics in the host overview the file host_view.php was changed as following:
... $g_metrics_group = array(); /* Addition of IPMI metrics */ $rrddir = "$rrds/$clustername/$hostname"; $metrics=add_ipmi_metrics($metrics,$rrddir); ...
