Alerts warn about vulnerabilities, incidents, and other security issues that pose a significant risk. Although stateful firewall technology is a powerful mechanism for controlling cyberthreats and preventing denials of service, controlling targeted exploitation. The trouble with being an incidental witness to the start of something that later becomes worldchanging is that at the time you are rarely aware of what.

Top 2. 5 Best Linux Performance Monitoring and Debugging Tools. Ive compiled 2. 5 performance monitoring and debugging tools that will be helpful when you are working on Linux environment. This list is not comprehensive or authoritative by any means. However this list has enough tools for you to play around and pick the one that is suitable your specific debugging and monitoring scenario. SARUsing sar utility you can do two things 1 Monitor system real time performance CPU, Memory, IO, etc 2 Collect performance data in the background on an on going basis and do analysis on the historical data to identify bottlenecks. Sar is part of the sysstat package. The following are some of the things you can do using sar utility. Collective CPU usage. Individual CPU statistics. Memory used and available. Swap space used and available. Overall IO activities of the system. Individual device IO activities. Context switch statistics. Run queue and load average data. Network statistics. Report sar data from a specific timeand lot more. The following sar command will display the system CPU statistics 3 times with 1 second interval. The following sar b command reports IO statistics.

More SAR examples How to InstallConfigure Sar sysstat and 1. Useful Sar Command Examples. Tcpdumptcpdump is a network packet analyzer. Using tcpdump you can capture the packets and analyze it for any performance bottlenecks. The following tcpdump command example displays captured packets in ASCII. A i eth. EN1. 0MB Ethernet, capture size 9. IP valh. 4. lell. P 1. 45. 72. 39. 47. E. i. 9. V. P. h. E. U. g. G. 7KA. A. L. 1. 4 3. 4 5. IP valh. P 1. 16 2. 321. E. V. P. h. 7. X. Im. S. g. u Oamp. Ba. E. R. V. OWp. Using tcpdump you can capture packets based on several custom conditions. For example, capture packets that flow through a particular port, capture tcp communication between two specific hosts, capture packets that belongs to a specific protocol type, etc. More tcpdump examples 1. TCPDUMP Command Examples. Nagios. Nagios is an open source monitoring solution that can monitor pretty much anything in your IT infrastructure. For example, when a server goes down it can send a notification to your sysadmin team, when a database goes down it can page your DBA team, when the a web server goes down it can notify the appropriate team. You can also set warning and critical threshold level for various services to help you proactively address the issue. For example, it can notify sysadmin team when a disk partition becomes 8. Nagios also has a very good user interface from where you can monitor the health of your overall IT infrastructure. The following are some of the things you can monitor using Nagios Any hardware servers, switches, routers, etcLinux servers and Windows servers. Databases Oracle, My. SQL, Postgre. SQL, etcVarious services running on your OS sendmail, nis, nfs, ldap, etcWeb servers. Your custom applicationetc. More Nagios examples How to install and configure Nagios, monitor remote Windows machine, and monitor remote Linux server. Iostatiostat reports CPU, disk IO, and NFS statistics. The following are some of iostat command examples. Iostat without any argument displays information about the CPU usage, and IO statistics about all the partitions on the system as shown below. Linux 2. 6. 3. 2 1. Canon Scan Software For Windows 7'>Canon Scan Software For Windows 7. Device tps Blkreads Blkwrtns Blkread Blkwrtn. By default iostat displays IO data for all the disks available in the system. To view statistics for a specific device For example, devsda, use the option p as shown below. Linux 2. 6. 3. 2 1. Device tps Blkreads Blkwrtns Blkread Blkwrtn. Mpstatmpstat reports processors statistics. The following are some of mpstat command examples. Option A, displays all the information that can be displayed by the mpstat command as shown below.

The following are some of vmstat command examples. To execute vmstat every 2 seconds for 1. After executing 1. You should install sysstat package to get iostat and vmstat working. More examples 2. Examples. PS Command. Process is a running instance of a program. Linux is a multitasking operating system, which means that more than one process can be active at once. Use ps command to find out what processes are running on your system. The following are few ps command examples. Use u option to display the process that belongs to a specific username. When you have multiple username, separate them using a comma. The example below displays all the process that are owned by user wwwrun, or postfix. UID PID PPID C STIME TTY TIME CMD. Mar. 09 0. 0 0. Mar. Mar. 09 0. 0 0. Mar. Mar. 09 0. 0 0. Mar. Mar. 09 0. 0 0. Mar. The example below display the process Id and commands in a hierarchy. ASCII art of process tree. From this tree, we can identify which is the parent process and the child processes it forked in a recursive manner. More ps examples 7 Practical PS Command Examples for Process Monitoring. Free. Free command displays information about the physical RAM and swap memory of your system. In the example below, the total physical memory on this system is 1. GB. The values displayed below are in KB. Mem 1. 03. 46. 24 1. Swap 2. 03. 16. The following example will display the total memory on your system including RAM and Swap. In the following command option m displays the values in MBoption t displays the Total line, which is sum of physical and swap memory valuesoption o is to hide the bufferscache line from the above example. Mem 1. 01. 0 9. Swap 1. Total 2. 99. TOPTop command displays all the running process in the system ordered by certain columns. This displays the information real time. You can kill a process without exiting from top. Once youve located a process that needs to be killed, press k which will ask for the process id, and signal to send. If you have the privilege to kill that particular PID, it will get killed successfully. PID to kill 1. 30. Kill PID 1. 30. 9 with signal 1. PID USER PR NI VIRT RES SHR S CPU MEM TIME COMMAND.
