AWS Systems Manager State Manager is a secure and scalable configuration management service that automates the process of keeping your Amazon EC2 and hybrid infrastructure in a state that you define. In our solution, we will use a state manager for running custom scripts for monitoring and alerting through the Event Bridge + SNS solution. […]
Unix Monitoring tools
Cloudstats.me – The Next-Gen Server Monitoring Platform
Cloudstats.me is the Next-Gen server/website monitoring platform which suits for Linux, windows servers and enterprise websites. I have been worked with several enterprise monitoring tools but Cloudstats stands out with it’s simplicity. You no need to spend thousands of dollors to buy the monitoring software and hire the resources to setup the monitoring services platform. Also […]
Solaris Process Inspection Commands
Oracle Solaris provides many utilities for inspecting the state of process which are running on the system.Using the process inspection commands ,we can dig in to the process in detail manner for in depth troubleshooting.Here we are going to see many process introspection command which will very handy on application trouble shooting.This article is based on Solaris internals book. Please see […]
Solaris Process controlling – proc tools
In the last post, we have seen about process status using prstat.But here we are going to see how to control the process using pid in Solaris Many of the Solaris administrator may thinking how to freeze the process ? Some beginners may still have doubt that how to kill the process? Some of them may still wondering how start […]
Solaris Processes Monitoring – prstat
Solaris has number of tools to examine process details and those just reading the /proc directory. These tools are very useful in application troubleshooting and analyzing the system performance. This article is based on “Solaris™ Internals: Solaris 10 and OpenSolaris Kernel Architecture” book. I would strongly recommend this for all the Solaris administrators. Here we […]
Solaris 10 – Local zone wise utilization Report using zonestat
I am sure many of the Solaris administrators will break their head in an order to find Solaris local zones wise resource utilization details on oracle Solaris 10. Because there is no simple inbuilt tool to find these details in Solaris 10 (Apart from prstat -Z). I just come across Jeff Victor’s Blog and found this […]
Solaris – Memory & Swap Usage Script
How to find the exact memory and swap usage of Solaris server? Solaris uses the memory as /tmp and swap will be calculated along with physical memory. We need to use the right commands to figure out the utilization of both. “top” is one if the best monitoring tool but it’s not inbuilt in Solaris 10. I have created […]
KSAR – Graphical SAR analysis tool (Identify Solaris Bottlenecks )
The SAR is very useful tool to monitor CPU,memory,disk I/O,network resources all the time on Solaris server.But how do you analysis sar output ? Off-course you can use sar commands to see various system resource usage using sar output files.(Ex:Like sar -f file_name to see CPU usage,sar -r to see memory usage).But we are expecting more than this.In Solaris we do […]
How to calculate SAR and VMSTAT memory values
Most of the UNIX beginners are very confused with sar and vmstat outputs.In most of the occasion they are not able to determine the free memory and free swap in order to find the memory bottleneck.Not all the time “top” command will give right values. Ksar graphical tool also very useful to analysis bottleneck.SAR:Now we will see how to calculate free memory and swapFormula: Free memory […]
How to enable SAR(System Activity Reporter) in Solaris?
SAR:(System Activity Reporter) SAR is a legacy system monitoring tool which is used to report CPU activity, system loads average, memory/paging, LUN load, network activity.We can add SAR in crontab to monitor the server through out the day and this will help you to find the system disk I/O,memory utilization,CPU utilization any given time.Once you have the sar output files, you can use ksar graphical […]
