Calculate disk usage in different servers
Hello,
I'm writing a script to monitor different filesystems in multiple servers. And depending on the % free, my script will send an Alert email if % free is less than threshold.
I want to keep a input_feed_file which would have "server,filesystem".
If I run a script a host 'a', then I can find the file systems usage on that server. But I'm intrested to watch few more filesystems that are in host 'b'.
How do I find the disk usage from my script, of these filesystems which aren't on one single server.
I'm not inclined to use any monitoring tools, so I'm trying to accomplish this in one single Korn shell script.
-------------------------------------------
Example of Input file:
host_a,/export/appl/filesystem_a/
host_a,/export/appl/filesystem_b/
host_b,/export/appl/filesystem_y/
.
.
.
--------------------------------------------
Thanks in advance.

httest is script based. The following script examples can be but into a scripte i.e. sample.htt and can be called like
httest sample.htt
SIMPLE SCRIPT
Get a page and do expect return code 200 OK.
CLIENT
_REQ www.google.ch 80
__GET /search?q=apache HTTP/1.1
__Host: www.google.ch
__
_EXPECT headers "HTTP/1.1 200 OK"
_WAIT
END
CUT AND PAST SCRIPT
Cut and past from a HTTP stream, i.e we cut the apache host to access it in the second request.
CLIENT
_REQ www.google.ch 80
__GET /search?q=apache HTTP/1.1
__Host: www.google.ch
__
_MATCH body '<a href="http://([^/]*)/" class=l>Welcome! - The <em>Apache</em> HTTP Server Project' APACHE_HOST
_WAIT
_REQ $APACHE_HOST 80
__GET / HTTP/1.1
__Host: $APACHE_HOST
__
_WAIT
END
CLIENT SERVER SCRIPT
We can hold client and server in the same host. Actually multiple client and multiple server. Very useful to test forward or reverse prox-
ies. Or a webapplication which communicat itself with third party servers i.e. mail server.
This is a very basic selfcontained test you can run on any maschine.
CLIENT
_REQ localhost 8080
__GET /foo HTTP/1.1
__Host: localhost

_EXPECT "/foo"
_WAIT
__HTTP/1.1 200 OK
__Content-Length: AUTO
__
__Hello World
END
SSL SCRIPT
Of course SSL do also work with httest, just put "SSL:" before port.
CLIENT
_REQ localhost SSL:8080
__GET /foo HTTP/1.1
__Host: localhost
__
_WAIT
END
SERVER SSL:8080
_RES
_EXPECT "/foo"
_WAIT
__HTTP/1.1 200 OK
__Content-Length: AUTO
