 |
|
Hi,
I have 5 AIX to supervise, i need to know cpu, but i must not write any file on the AIX systems, there are no oid about processor or cpu load, plus i have been forbidden to install net-snmp or another softwares.
So i use telnet. I would like to know if the scripts are convenable.
There are 2 files in the usr/local/apache/htdocs/cacti/scripts/remotecpu directory.
file cpu_req.php
| Code: |
<?php
$ip=$argv[1];
$login=$argv[2];
$passwd=$argv[3];
$path_list="/usr/local/apache/htdocs/cacti/scripts/remotecpu/list";
$path_listcpu="/usr/local/apache/htdocs/cacti/scripts/remotecpu/listcpu";
function getcpu($ip, $login, $passwd, $path_list)
{
exec("sh remotecpu.sh $ip $login $passwd > $path_list ");
}
function cleanlist($path_list, $path_listcpu)
{
exec("more $path_list | sed /[A-Z]/d | sed -e '/[0-9]/!d' > $path_listcpu");
}
function sumcpu($path_listcpu)
{
static $sum = 0;
$fp = fopen($path_listcpu, "r");
whiles(!feof($fp))
{
$sum += fgets($fp, 4096);
}
fclose($fp);
print $sum;
}
getcpu($ip, $login, $passwd, $path_list);
cleanlist($path_list, $path_listcpu);
sumcpu($path_listcpu);
?>
|
file remotecpu.sh
| Code: |
#! /bin/sh
(sleep 2
echo "$2"; sleep 5
echo "$3"; sleep 5
echo "ps gu | tr -s ' ' | sed -e 's/[ ]/:/g' | cut -d: -f3 | sed /0.0/d | sed /[Aa-Zz]/d"; sleep 5
echo "exit") | telnet "$1"
#korn shell ksh
# ps gu | tr -s ' ' | sed -e 's/[ ]/:/g' | cut -d: -f3 | sed /0.0/d | sed /[Aa-Zz]/d
#Bourne shell
# ps -aux | tr -s ' ' | sed -e "s/[ ]/:/g" | cut -d: -f3 | sed /0.0/d | sed /[A-Z]/d
|
| Code: |
php cpu_req.php ip login passwd

You need a telnet server on the remote system.
I have a problem because of the time (sleep).
Does someone know how to make a telnet command in a script whithout sleep command?
If the remote system are busy or if the telnet server is down, the request will fail. |
