I'll try that in another way; feel free to give me your hacks for it:
<?php
$file = file_get_contents( "./ip" );
$line = explode( "\n", $file );
## Number of log entries
$total = 0;
$unavail = 0;
$unavaillog = FALSE;
## Establish the standard difference between log entries of 5 minutes
$diff = 300;
## Add 5 because cron often is off by a couple of seconds
$maxdiff = $diff + 5;
$downtime = array(array());
Done the log parser:
## Count variable for iterations of downtime
$cntdown = 0;
foreach( $line as $val ) {
$bits = explode( "\t", trim( $val ) );
if ( $bits[0] && ( $bits[1] == "S" || $bits[1] == "U" ) ) {
$ctime = $bits[0];
if ( $total == 0 ) {
$firsttime = $ctime;
$ptime = $firsttime;
}
$diftime = $ctime - $ptime;
## Calculate the amount of time the server has
been down.
if( $diftime > $maxdiff ) {
print $diftime ."\n";
$missed = $diftime / $diff;
$unavail += $missed;
$total += $missed;
if ( $unavailog ) { }
else {
$downtime[$cntdown][start] = $ptime;
$unavailog = TRUE;
}
}
if( trim( $bits[1] ) == "U" ) {
if ( $unavailog ) {
}
else {
$downtime[$cntdown][start] = $ctime;
$unavailog = TRUE;
}
$unavail++;
}
else {
## Once the down time has finished
if ( $unavailog ) {
$downtime[$cntdown][finish] = $ctime;
$downtime[$cntdown][diff] = $downtime[$cntdown][finish] -
$downtime[$cntdown][start];
$cntdown++;
}
$unavailog = FALSE;
}
$total++;
$ptime = $ctime;
}
}
## Last time is registered as the timestamp of the last entry
$lasttime = $ctime;
$firsttime = date( "j/n/y H:i", $firsttime );
$lasttime = date( "j/n/y H:i", $lasttime );
## Make sure the percentage is uptime, one decimal place
$percentage = number_format( ( 100 - ( ( $unavail / $total ) * 100 ) ),
1 );
print "$percentage% uptime from $firsttime to $lasttime\n";
## Need to make this look pretty
print_r( $downtime );
