Your SSDs are likely healthy, but the HP Smart Array P410 RAID controller is not compatible with every SSD. In particular, some SSDs report incorrect temperatures attributes to the controller that cause chassis fan and system thermal issues. In addition, any SATA device used on that controller will be downclocked to 3Gbps speeds from 6Gbps. So you're ...

No, PKIView.msc do not provide any automation means/capabilities. You have to write your own scripts. What I would suggest (sorry, no actual code, but a way to do this) is to consider the following plan and possible tools (assuming, you will use Windows PowerShell): enumerate all Enterprise Certification Authorities (by using ICertConfig interface) loop ...

Use the command: ss -neopt state established This will show you only TCP sessions in ESTABLISHED state, no piping to other commands required, so it's super fast. ss is better than netstat because the older netstat just reads from procfs which is subject to file locks. ss actually makes a query inside the kernel which is handled by the kernel scheduler ...

There are probably a great many ways to do this, but here's what comes to mind for me. It doesn't seem so hard. This might actually be a fun exercise. First, you want to geolocate the IP address. There are a few free ones such as HostIP.info and IPInfoDB (among MANY others). You should probably try and grab a zip code, or if you're international, then ...

The simplest metric is disk queue. It is basically the number of operations waiting in the queue to be written to disk. The rule of thumb is that if the queue has a sustained size that is greater than the number of disks you have in the array then you need more disk. All this can be measured using perfmon.

Personally I use syslog-ng to forward syslogs and cacti with SNMP and syslog plugin , to achieve this functionality - this allows for prioritising/highlighting of specific event types etc, and emailing upon certain events etc. Edit: if you do go down the cacti route, you may also find the threshold plugin useful; it can be configured to notify you when ...

Google Analytics has a realtime location view that'll let you drill down to country (and state/city in some areas). If you want to do it yourself, you'll have to combine GeoIP and some web development.

A check that returns SOFT CRITICAL does not trigger notifications, as it has not reached the max_check_attempts threshold. This is not a false positive; it is Nagios working as designed. This is quite normal (for many services, not just for your case). It's exactly why max_check_attempts exists. In your case, it's returning to normal within 3 minutes of the ...

You should not use S3 directly. You should put the S3 bucket behind CloudFront for best performance.

I think you're on the right track in with writing the time to a log file every second, but for the reasons you pointed out that may not be reliable. In addition to writing the time to a local disk, why not have your cron process reach out to a known stable system over the network and have that system log the request to disk? Something as simple as wget ...

Check also: 527875. netstat + grep is a good and simple option for a few connections but if you have a huge number of connections I would recommend ss as recommended in nixCraft. For instance: ss -s Total: 78 (kernel 79) TCP: 31 (estab 27, closed 0, orphaned 0, synrecv 0, timewait 0/0), ports 16 Transport Total IP IPv6 * 79 - ...
