View 3 Replies View RelatedI have a PROMISE TECH hardware raid card running a 4 disk RAID 10 array. I logged into today to check the drive statuses which were:
Drive 1: OK
Drive 2: OK
Drive 3: OK
Drive 4: OK, PFA
So they all look to be okay, but that 4th disk has PFA (I'm guessing that stands for predicted failure analysis) but I am not sure if that means its predicting a fail, or just stating that the technology is running?
Also, this array is the system drive on a server which has much too little memory, (there is usually 5-7GB PF swap during the day) and I'm concerned that the drives constantly under that stress are more prone to fail. They are 2.5" SAS 10k Fujitsu if that means anything.
I am wondering if anyone knows of any good system monitors for Linux. I will be installing several web and database servers at a branch office and would like to receive stats like system temperature, cpu load, memory usage, etc. Basically something to tell to warn me in the event of a hardware error. I am looking something with an easy-to-use web interface and ability to generate reports.

I'm not sure what the cause is, but I wouldn't be surprised if it's because they are a primary peer for Hurricane Electric and other budget carries who don't have much other Tier 1 peers (i.e. Xeex).
Any comments from current Global Crossing customers?
The server is idle, according to TOP.
Health center shows
Total usage
6056039.4% used 2198044.96
nginx CPU usage
156.5 % 3250.89
Mail server CPU usage
203.6 % 4844.61
MySQL CPU usage
12.2 % 10.28
Plesk CPU usage
164.6 % 95111.06
Getting tired of all the notifications plesk sends to my phone....
EDIT:
Happens everytime i reboot the server.
After about 15 minutes the stats normalise.
I spent a lot of time trying to not have alarm messages into spam folder.
already added address to my contacts
already mark it as important
already changed sender email... but
Plesk where take email for Alarm Message?
Because I changed email (external) with 1 internal, but update alert arrive with administrator email and now is not going to spam, but alarm email arrive with old email (external, that is marked as pishing) ....
i can't seem to get access to the health monitor in power user mode. As my plesk license was "upgraded" from a usual 11.x 10 Domains-License to new WebAdmin Package, i can't choose service provider view anymore. How can i get access to the health monitor now?

This is the log from /var/log/plesk/health-alarm.log
##################################################
2014-06-24T10:01:15+11:00 INFO (6): Server health parameter "Services > Panel CPU usage" changed its status from "green" to "red".
2014-06-24T10:21:16+11:00 INFO (6): Server health parameter "Services > Apache CPU usage" changed its status from "red" to "green".
[Code].....
I keep receiving emailed alerts with subject like:
"<server name> alarm level changed"
with content like:
Server health parameter "Memory > Real memory usage" changed its status from "green" to "yellow".
or
Server health parameter "Services > Apache CPU usage" changed its status from "red" to "yellow".
(and then a readout of the top command)
1) Where in Plesk can I see live alerts (or a historical log of these alerts)
2) Where can I change the settings (I think it may be too sensitive and the thresholds need to be adjusted)
3) I don't quite understand the alerts in general either, for example, the "Memory > Real memory usage", the TOP command output is for example:
top - 12:19:59 up 4:56, 1 user, load average: 0.21, 0.21, 0.21
Tasks: 255 total, 1 running, 254 sleeping, 0 stopped, 0 zombie
Cpu(s): 5.5%us, 0.7%sy, 0.2%ni, 92.8%id, 0.8%wa, 0.0%hi, 0.1%si, 0.0%st
Mem: 5967176k total, 2539756k used, 3427420k free, 134972k buffers
Swap: 4194300k total, 788k used, 4193512k free, 664916k cached
More than half the memory is unused, very little swap is in use. I don't even see a reason to be warning about this.
I need to sending health notification emails to another email.
I change admin : /usr/local/psa/bin/init_conf --update -email xxx@xxx.xx
Admin change, but health notification email not change.
My server has a small SAS disk(about 73G), if I use 90% diskspace of it, is it good idea, will it harm the physical HDD?

I have a one problem in my server . I use in Parallels Plesk v12.0.18_build1200140606.15 os_CentOS 6 I vps in systemOS CentOS6.6 Final Minimal and installing plesk health monitor show error in :

And I try the command

output problem is :

Health Monitor Module is installed and running on server, but not visible under Server Administration Panel > Home > Server Health on Plesk Panel 11.0.9 update #7. Is there a trick to configuring home to show it and/or a direct way to launch view of server health?

Any Unix FTP tool to get all files (files+subdirectories) from remote server with 1 line command?i'm using FreeBSD
View 1 Replies View RelatedIve recently switched from PC to OSX, i now own '2' Macs, a laptop and a G4 Quicksilver, although its CPU speed is slower and the Ram is lesser then my old PC, it performs much much quicker and more efficient.
The question is, i'm a web developer, i know very little about the back end goings on, such as System Administration, but i've got a few books on the subject which are aimed at Unix system administrators. Does UNIX cover both OSX and Linux (Debian mainly).
Eventually i want to be able to run my own server, i own a debian dedicated server, but its not my own, its the datacenter's and i dont really know enough to get down and dirty in the back end. Id like to be able to set up servers from scratch in the long run.
So would learning UNIX cover both OSX and Linux, im not bothered about Windows, i don't plant to use a Windows machine again.
I am looking for better disk performance. Due to the tight budget, I have to choose one of following options as my disk choice:
2 SATAII disk w/RAID0, 7200rpm, 32M cache for each disk
1 SAS disk, 15000rpm, 16M cache.
which one will be better and how better if other things(hardware & OS) are same?
can a Xen disk image be converted to a diskpartition?
Someone is asking whether I can host his disk image at his current host, which he is leaving for poor I/O (wonder why that would be ). I can host a diskimage, but I don't like diskimages (slow, and 100GB isn't very 'comfortable' either). Is there any way out there to convert a disk image into a normal partition?
is there any performance difference using php on unix and (isapi)windows platform?

Is there a way where i can view which IP connected to my server the most? I need to find out if there is certain IP keep hitting my mail server until it crashed.
Preferably the software could sort out the highest hit IP then to the lowest.
I`ve been playing with Debian and FreeBSD for couple weeks so far. As a noobie I`d like to ask you what distribution you prefer for web server? I know that it is said "the best is the one you know better" but in my situation it is hard to say that I really know either Debian or FreeBSD.
So what would you recommend in my situation (new to *unix topic) if I have to set web server for a company site?
I`m mostly interested in security, relatively easy to configure/secure/find info how-to, easy to update soft apache/php/mysql.
which hosting is better - Windows, Unix or Linux?

I'm a Unix newbie so please forgive me if this is a really dumb question but I haven't quite been able to figure it out...
I'm trying to set up a form script to replace formmail on the server. I've set it up in the cgi-sys bin. I chmod the script 755, but when I try to call it I get 500 error messages.
I was looking at the permissions and I noticed that all the other scripts have the "wheel" setting.. such as:
197633 -rwxr-xr-x 4 root wheel 3479620 Dec 22 03:04 _formmail.cgi*
The new form I added as "root" instead of "wheel":
1280150 -rwxr-xr-x 1 root root 12342 Mar 1 21:46 mycontactform.pl*
How do I change it so that "mycontactform.pl" is in the "wheel" group so that it works? Anything else I should know/do to make this secure? I don't know enough about the permissions to change this. I want all the customers on the server to be able to use the new form.
