We have configured nagios with check_load NRPE plugin to monitor server load. It reports when load is high, but does not have option to take a snapshot top processes ( like top commmand) at that time. Any good nagios NRPE plug-ins for that ? Asked by nitins You can do it with event handlers. First, add an event handler for your Load average definition: define service{ use generic-service host_name xx service_description Load_Average check_command check_nrpe!check_load event_handler [...]

Running on Ubuntu. I need to monitor my program CPU and RAM , my prefer way is to monitor by SNMP. Does someone know the OID for program CPU and RAM(not total)? If there isnt so what is the simple way to get ? parse ps command? Asked by user1495181 Per-process performance information is found in HOST-RESOURCES-MIB::hrSWRunPerfCPU and `HOST-RESOURCES-MIB::hrSWRunPerfMem. Given a PID, $PID, you can run: snmpget hostname HOST-RESOURCES-MIB::hrSWRunPerfMem.$PID Or you can walk the whole [...]

I have GNU/linux Box (linode VPS running Debian) with PHP, Apache, MySQL and Varnish (and app/site that use those) is there a tool that will save or monitor load times of web server responses? Asked by jcubic Check out Apache’s LogFormat directive. It allows to log the time taken to serve the request (%D and %T). This can be used for monitoring your server’s response time. It will for example tell you if your server [...]

I’m trying to find the best way to monitor my MS SQL server. I have been using pingdom for my web server and want to look at something else. I have done a lot of googleing but they all seem to be the same. Was hoping someone could tell me their good and bad stories that might make it easier to pick one. It is just for the MS SQL server. Just need to know [...]

I think the tool name is SARS? I have CPanel host and need to monitor loads and such. What tool and how do I do it?

I don’t understand why my htop meter is full already. I’m not even running some task. Here’s the screenshot of my htop: http://i.imgur.com/F56uB.png The green meter shows used memory, the blue meter shows buffers, the yellow meter shows cache. it seems that the cache have used up all my memory here. Or am I just confused? Because the numeric number shows 48/494MB. So what is happening here? Should I increase the memory of my server? [...]

I’ve got a couple of servers running SQL Server 2005 Enterprise and I’d like to monitor them remotely using Perfmon (Windows’ Performance Monitor). On my machine, I have an instance of SQL Server 2008 R2 Developer, and I noticed that there are a bunch of SQL Server specific performance counters, like MSSQL:Buffer Manager, MSSQL:Databases, MSSQL:Memory Manager, MSSQL:Transactions, MSSQL:Wait Statistics, etc. If I connect to both servers using Remote Desktop and open Perfmon at the server, [...]

I’m using WMI to monitor Windows Server 2003 and Windows Server 2008 hosts. I got all the info I wanted but the disk I/O performance. I’ve tried quering the “Win32_PerfFormattedData_PerfDisk_LogicalDisk” for the “AvgDiskQueueLength”, but I always get “no key” result. The WMI service is running on both systems and I can connect to it using wbemtest without any errors. Have I missed something or am I doing something wrong? AvgDiskQueueLength is a property of the [...]

Linux has a notion of Load Average which is defined as: System load averages is the average number of processes that are either in a runnable or uninterruptable state. A process in a runnable state is either using the CPU or waiting to use the CPU. A process in uninterruptable state is waiting for some I/O access, eg waiting for disk. The averages are taken over the three time intervals. Load averages are not normalized [...]

This is something that’s always bothered me, so I’ll ask the Server Fault community. I love Process Explorer for keeping track of more than just the high-level tasks you get in the Task Manager. But I constantly want to know which of those dozen services hosted in a single process under svchost is making my processor spike. So… is there any non-intrusive way to find this information out? Yes, there is an (almost) non-intrusive and [...]
