Take a look a ITwatchdogs. Their weather goose line looks very nice. They monitor temp, light, sound, humidity, etc. Here's a list of vendors (not APC) that have other products. What I use in my data center appears to be a discontinued model. What ever you end up using, make sure that: They use SNMP, not some special protocol. Have remote temperature ...

One simple way to get Windows Server 2008 to send low disk space e-mail alerts is to use Task Scheduler and the System Log. If the free space falls below the percentage specified in HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\DiskSpaceThreshold, an event is recorded in the System Log that can trigger a task to send an e-mail message. ...

This depends slightly on the operating systems you're running on the servers, but in general, it is possible to obtain alerts from HP ProLiant servers and Smart Array RAID controllers. The full driver and software support listing for your DL380 G5 systems is listed here. SNMP and a monitoring solution is the best approach... But you can augment that with ...

You could use something like LogWatch. Or even a simple script like this (it's pseudo code you'll need to modify it for your enviroment): #!/bin/bash GREP_STRING=`grep -c <error string> <acpid log location>` if [ $GREP_STRING -ne 0 ] then <send email notification> fi Put that in cron to run every hour or so and you should get ...

What you're proposing is to effectively re-implement your monitoring system (by feeding the current system's alerts into another monitoring system that's smart enough to know something is wrong if it's not constantly reassured that everything is fine). This almost certainly is not what you need. What you need is a combination of on-site and off-site ...

I think monitoring the event log is the easiest scenario. You can pick your poison (Microsoft System Center Essentials, Nagios, etc.) and have it send out an SMS alert when you come across Event 528's and 540's of logon type 10. Monitor 538's (again of type 10) in order to see them log off. Reference: ...

You can use OSSEC HIDS to set up rules on log files and, at the same time, get security information from your host. Setting it up is very easy: Download the source Uncompress it and run ./install.sh Choose local install Answer the questions (email, checks, etc.) Edit /var/ossec/rules/local_rules.xml as specified below Start OSSEC with ...

There isn't one standard, at all. You need to define what you're monitoring for your clients and how you'll do it. If you're making sure their websites are up, a hosted solution (is that what you mean by "cloud") is probably best. The hosted monitor will hit the websites from one or multiple locations and measure the response times. If you're doing ...

Nagios supports exactly what you want. Take a look at passive checks and freshness. Basically, you define a host and service for your job, and tell Nagios that the service is passive and has a specific freshness threshold (e.g. 26 hours.) Whenever your process runs, have it submit a "OK" result to Nagios. Nagios keeps track of when the OKs are submitted, and ...

You associate an SQL Agent "alert" to detect the error, which then sends an email to an "operator" or runs a job. You use sp_add_alert but the main info is here: Monitoring and Responding to Events

A couple of specific answers and a suggestion ... 1- There are several makers (linked in other answers) of standalone temp and humidity monitoring devices. These are pretty simple .. typically you mount them where you want to monitor, plug them into the network, and configure them to email alerts. They work well. 2- Most servers can raise SNMP alerts ...

Try the --errors-only flag which should greatly reduce the amount of text spit out by this plugin. -e, --errors-only Display only devices/mountpoints with errors This seems to do the trick for me. Note the drastic difference in the output: # /usr/lib64/nagios/plugins/check_disk -w 20% -c 10% DISK WARNING - free space: / 37167 MB (96% inode=98%); ...

Nagios runs external commands without any ENV. To simulate this, you can try running your manual test via "env -i ". You seem to already know this, because you are explicitly setting PATH and HOME. You should try to avoid this, and just use full paths in any scripts/commands/etc. You also might need to escape some of the non-alphanumeric characters in your ...

I can think of a few different ideas. The "built-in" functionality in Windows XP that yoy're looking for is the Network Location Awareness service. Having said that, though, you'll need custom code to take advantage of it, because it's just an API and not a finished "solution". You could use a "ping probe" tool to poll the wired NIC IP addresses on the ...

Yes. A more precise answer will require more detail, because there are several ways to go about it,but from the sounds of things you really need a moniroing system. At a minimum, look into setting up an SNMP server which all your clients can report to and send an alert out over SNMP if the status of their wired connection changes. You could even do ...

You could look at setting up a jabber server and installing a jabber client on each users machine. Logins can be tied to AD or to another LDAP system or a database. As it's open source if the config file doesn't let you disable the features you want disabled just disable or remove that block of code from the source.

We use Nagios for this. The check_http program included with it knows how to talk SSL, and can return a "warning" or "critical" status based on how close the certificate is to expiration. From the command's help output: CHECK CERTIFICATE: check_http -H www.verisign.com -C 14 When the certificate of 'www.verisign.com' is valid for more than 14 days, ...

I checked out several of the options mentioned on this page, and ended up using something far simpler: swatch. Those other systems are great for dealing with existing system logs, or with software where you don't have control over the output. I just didn't want to write a bunch of code to do email notifications just yet. So I just created a swatch file ...

Set up a Pingdom monitoring service to send you emails and SMS messages when things go wrong. Also set up something like Nagios to alert on internal services, also set up to alert via sms, using a provider such as Clickatell.

Rather than creating an alert for just this one item you should consider setting up Nagios or similar. You can then have it monitor just about anything you like and alert you when something is outside your predefined parameters. The relatively small amount of time needed to set it up will be more than repaid by freeing you from having to manually monitor and ...

In a former life without monitoring systems and automatic warnings I had use for this snippet: #!/bin/sh df -H | grep -vE '^Filesystem|tmpfs|cdrom' | awk '{ print $5 " " $1 }' | while read output; do echo $output usep=$(echo $output | awk '{ print $1}' | cut -d'%' -f1 ) partition=$(echo $output | awk '{ print $2 }' ) if [ $usep -ge 90 ]; then ...

Define a serviceescalation with notification_interval set to 120 when the service is in CRITICAL state: define serviceescalation{ host_name xx service_description disk_free notification_interval 120 . . escalation_period 24x7 escalation_options c }

The standard way is to have everything on one line. You only have two options: define a check for each disk (I know is not what you want but I still find this the best solution) write your own plugin or a wrapper around check_disks which parses the output: you can then for example put the disks below the threshold in the status lines or shorten the output ...

Chopper got it right - In VCenter, go to the Alarms tab, then click on definitions. Double click the entry called: "Datacenter Usage on disk" On the Actions tab, click Add, and a new action will be created. Hit the drop down for the new action, and change it to "send a notification trap". Comes in handy, if you don't have any other monitoring ...

Download and install Splunk (www.splunk.com) on the server. It's similar to logwatch, but provides you with a search engine for your logs. You can configure it to index your logs, you can then search the logs and find patterns, find the errors, and then look at what other logs are doing at that specific point of failure. It can also be set to send alerts ...

I would suggest Nagios its what we run where I work for monitoring multiple machines with are network. Its very good i've not used it specifically for what your doing but you can certainly set it up to email you when errors occur. There is a guide here for installing it on Ubuntu http://beginlinux.com/blog/2008/11/install-nagios-3-on-ubuntu-810/ and one ...

+1 to Joseph Kern's answer. We use one of ITWatchdog's systems,but I've used other systems as well, and the general idea is great. ITWatchdogs, and a lot of other vendors, make use of the Dallas 1-wire bus to drive their sensors. The actual sensors are available from Farnell etc for very low prices, and they basically attach to a piece of cat3 cable. You ...

We use the MiniGoos products from http://www.itwatchdogs.com/. I will admit I wasn't involved in the evaluation process for these, but I really like the product. They allow multiple temperature sensors and they have some nifty add ons like air flow monitoring (which we aren't currently using) and things like door open/close detection (which we are). They ...

If you want a cheap solution, you can buy USB thermometers for about 10USD. I've got a TEMPer device. I've not got around to using it yet, mostly because it's not entirely supported under Linux. Tollef Fog Heen wrote some support, but I haven't checked to see if it's in the kernel yet. It does ship with Windows drivers, so it just a matter of hooking it up ...
