hi

Am trying to find os app with good gui which can probe web,dns and other services and also monitor via ICMP and send me auto-emails or sms. do you know any. i found many can run over windows but i need one that can run over linux and be customized also without snmp and agentless

Thanks

Define "probe web,dns and other services "; what exactly do you want to measure/monitor?

ICMP just tells you if the network stack on the target is working (ie ping cmd).

It sounds like the usual suspects like Nagios would do.

Just to add that Nagios (& similar) is a monitor mgr and many of the scripts/cmds it can run do use SNMP, but its not compulsory to use those.
I'd also note that snmpd is pretty much part of the std install on systems as a rule; that's why people use those scripts/progs; no need to add anything to the target systems.

The idea i don't need snmp or agent. probing for example making sure service is running as am open http connection with web server or digging through dns to make sure its working.

Nagios is good also zenoss but all of them use snmp

Nagios can use SNMP but doesn't have to.

For example, one of the standard plugins:

Code:

#./check_http --help
check_http v1.4.15 (nagios-plugins 1.4.15)
Copyright (c) 1999 Ethan Galstad <nagios@nagios.org>
Copyright (c) 1999-2008 Nagios Plugin Development Team
        <nagiosplug-devel@lists.sourceforge.net>

This plugin tests the HTTP service on the specified host. It can test
normal (http) and secure (https) servers, follow redirects, search for
strings and regular expressions, check connection times, and report on
certificate expiration times.

Oh, and you mention DNS

Code:

# ./check_dns --help
check_dns v1.4.15 (nagios-plugins 1.4.15)
Copyright (c) 1999 Ethan Galstad <nagios@nagios.org>
Copyright (c) 2000-2008 Nagios Plugin Development Team
        <nagiosplug-devel@lists.sourceforge.net>

This plugin uses the nslookup program to obtain the IP address for the given host/domain query.
An optional DNS server to use may be specified.
If no DNS server is specified, the default server(s) specified in /etc/resolv.conf will be used.

As I and TenTenths have said

which pretty much goes for all those tools AFAIK.

netcat (nc) and dig commands can "probe". No "good gui" unless you count the terminal.

zenmap, doesn't seem to have an email/sms widget.

Tons of online domain pingers/checkers that can accommodate you, such as http://www.host-tracker.com/

Zabbix is what I use and it does all this, but it is probably overkill for you.

ICMP isn't a valid method of checking anything, since a LOT of devices now drop icmp requests.

I <3 Nagios.

It can be run agentless and without snmp, but that seriously cripples its abilities. It will do at the least what you are requesting without said.
