System activity monitoring tools - top, iotop, ntop, sar, collectl, etc - may be a good reference to judge the system activity when the system transitions to sleep state.But if I make the system transition to sleep state when i/o activity is zero during 15 minutes, for example, it won't sleep forever because slight i/o by daemons, etc occurs continuously even if no user i/o.So how can I judge the system activity to change the state by using those tools?
I just need to ask about any existing tool in linux which can show us the CPU memory and swap utilizations of overall system for particular time duration and generate graphs.?i m a student of computer science and want this information of resource utilization for my project..kindly reply if any of u liux fans knows about such tools.
I have a Centos router and I want a tool that can give me reports accessible from a browser about the users web activity. I need two type of daily reports:- list of web pages accessed by each local host- list of all web pages accessed by all local hosts and lit of local hosts that accessed one specific web pageI tried ntop and is not really suitable for what I need. Maybe it can do what I need, but I have to make several improvisations.
dear can someone highly gui or text base/command line tool that use as "isp bandwidth monitoring tools in linux".i do have leased line,frame relay, wireless linke,dsl too. i want to monitor what is uploading and downloading.
I am looking for some monitoring tools (such as disk usage,memory usage, cpu,etc) for my linux machines. I came across two tools, cacti and splunk.Which one is better ? It will be nice if you can also let me know the reason.
I am currently running a 64-bit Fedora 14 server which hosts a game server, a voice server, and remote desktop functionality, each on a distinct TCP port. I am currently using the built-in firewall to deny all traffic other than ICMP ping/pong and TCP traffic on those specific ports.I am looking for a graphical application which will let me monitor any connections being made to my server in order to keep an eye out for possible security concerns. To be more specific, I'd like to be able to see the source IP addresses, TCP/UDP ports, and individual bandwidth in use by external connections being made to the server, along with any other information that might be helpful in identifying a possible intrusion attempt.
I have a scenario where I want to monitor at disk performance (cpu and memory also if possible) on a RHEL 5 server functioning as a NAS. I have several machines that backup content to this server via scheduled cronjobs and I'm curious to see if the machine is hitting a bottleneck under load.I attempted to setup cacti on one of our LAMP servers and had a miserable time due to running PHP 5.3 and deprecated function issues.Can anyone recommend an alternative keeping in mind I have only very basic experience with SNMP?
I have a third party program (tightvnc) which I want to monitor and detect if it loses a connection with a client. I don't care if the client has the program open but isn't doing anything with it, I only want to know if the actual TCP connection is lost.
Since TCP takes forever to die on it's own I was thinking the best way to detect if a connection is lost is by bandwidth the bandwidth on the tcp port allocated to the VNC connection. Are there any tools built in to redhat (RHEL 5.2) which I could use to do this? Since I don't have full control of the operating system I would prefer to use built in tools rather then trying to get a new tool installed.
We have few servers and we need to monitor mysql and ping (port 80) on our servers to send us email notification and also we need sms notification when something is wrong, we can ask our developer to write sms notification (which is very important for us) because we already have the API and only need a output from a good monitoring tools to show to our developer and ask him to write the notification program.
Our primary sever is centos with WHM installation and hosts about 600 websites.(need to monitor mysql & port 80 on this.)The secondary one is windows server with virtuzzu installation and host about 15 windows VPS (The server crashing some times and we need to findout its out of service ASAP .)Should we use monitoring websites such as hypersins.com or siteuptime.com (which is a little expensive for us especially because of international sms rates.) or there is nice tools we can easily configure and use !
I have Karmic installed on three different computers (work, home and laptop), but on my home desktop there is a strange performance problem. During disk activity it sometimes becomes completely unresponsive. The mouse cursor doesn't even move. It actually seems fine when it first boots up, but it gradually gets worse as I use the computer for a while until it eventually becomes completely unusable. I'm only having trouble on the one system.The drive in the system is SATA, and I already checked to make sure DMA was on. It is a x86_64 kernel.I tried adding noapic to the kernel boot line after some googling, but it seemed to have no effect
I am working on a program lets say programX which must run when the computer is not in use. I want to develop a monitoring program to monitor if there is user activity on the system so that it can stop the programX from running when the user is using the system and start programX when there is no user activity. Is there a way to determine this in linux?
My system started running at 75 % CPU (its normally 20%), so I opened a terminal and looked at 'top', there are many processes running as root, the one thats sucking the CPU is this:'user'- root, 'pid'-2963, 'command'-X. below that there are a few processes of my user account, then alot more 'root' processes.
I have an auditing problem. I am required to be able to track user account modifications (creates, deletes, password changes, etc.) My team and I implemented auditd 1.7.17 and borrowed an existing rule set from /usr/share/doc/audit-1.7.17/nispom.rules. What we're seeing is that user account activity from the command line is retrievable by doing an 'aureport -m'. However, doing the same through the GUI, 'aureport -m' does not display the activity. So I have two questions:1. Is there another location I should be looking to find the user creation activities when using the GUI?2. Is there a way to make the activity using the GUI be captured in /var/log/audit/audit.log so 'aureport -m' can report it?Someone suggested a PAM configuration change, but was not able to tell me what change to make.
I keep noticing disk activity every roughly 1 to 3 seconds even though there is "nothing" going on. Of course, I run a number of "system" and "user" application packages - Apache2, MySQL, Browsers (Opera, IceWeasel), an SMB client and server, OpenOffice 3.0RC8 being the most prominent ones. I wonder what might be the cause for this constant disk activity which happens even when none of the applications do any noticeable work at all. Is there a way to determine the process that does those disk read/writes?
Just after I boot up I get this wierd HDD activity that lasts for some time during which my system runs at snail Pace and or Hangs. After a while the activity stops and things are good and then randomly it all starts again. I have read some forum post on constant HDD activity but they do not seem to apply to my problem. I am Running 11.3 with a quad core AMD 64bit CPU and 4GB of memory.
I'm running Slackware 13 with a custom kernel based off of 2.6.32.3. I tend to leave my system on 24/7, as well as my web browser. Originally it was Firefox and now it is Google's Chrome. Usually about a day of leaving the web browser open my HD activity spikes so high that I can barely do anything on the system until I kill the web browser. This has been happening with both Firefox AND Chrome! As soon as the browser processes are killed, the system returns back to normal.
I want to know which was the best networking monitoring tool in linux wright now im using opennms . i like to try out with any other monitoring tool can somebody say which one is best one followed in linux industry
I have several systems I would like to monitor. Right now I just care about the system time.
I am going to start off by simply monitoring the system time and want my monitoring SW to alert me if it differs more than 5 minutes from the local time on the monitoring system. (My systems seem to have a huge time drift even after I setup NTP) Will Nagois do this?
In the future I would also like to monitor such things as disk usage (capacity and how busy), memory use, various process' I want to know if a process dies or not. Will Nagois do this?
If not do you have any recommendations on SW for this task.
I tried to do a scheduled software update several times today (8/20/11) and nothing seems to download, though I do get the "Downloading" PackageKit dialog message (the System Monitor shows practically no network activity). In between tries I downloaded some 600 MB .iso files (about 10 minutes each) so I know my internet is working properly. That leaves either PackageKit got hosed in my last update, or servers are down.
I need to monitor resource of my server.I have found munin and sysstat, Does munin use systat? or they are different package?because in some documents I have found on net,for installing munin, systat is needed !!for example on RedHat based distor, sysstat package is needed! but on debian is not needed
I setup apache server in order to gain access for the smokeping network monitoring system. I am accessing the system using [URL] But I want this page access using [URL]
My httpd.conf file looks like : Alias /smokeping/ "/usr/local/smokeping/htdocs/" <Directory /usr/local/smokeping/htdocs/> AllowOverride AuthConfig DirectoryIndex smokeping.cgi Options -Indexes ExecCGI </Directory>
I just installed Ubuntu Tweak & I can't find how to access it.I read that it is under Applications - System Tools- Tweak My problem is when I click Applications the only items that are there is
I have already developed file type filtering functions through squid. Now I want to deal with content filtering aspects... What tools are available there for so in linux?
