![]() Iostat -d command is used to display the device utilization report. The iostat -d command is used for monitoring system input/output device loading by observing the time the devices are active related to their average transfer rates. This command is mostly used by Linux System Administrators. Iostat commands are useful for changing system configuration to better balance the i/o load between physical disks. The iostat command in Linux lets you monitor CPU utilization and I/O (input/output) statistics of all the disks and file systems. We can install easily under package “ sysstat” vmstat Vmstat must not be present in your Linux System but no worries. The vmstat command is a Linux Utility for displaying statistics related to memory consumption, disk usage and other system information. Pressing qwill simply exit the command mode. And Lower half contains a list of the currently running processes. Where the top half portion will contain the statistics of processes and resource usage. When we will run this command it will open an interactive command mode. Let’s go through some of the most used Linux command-line utilities to diagnose network and performance-related issues Linux Monitoring Commands 1. Please feel free to ask any questions or make suggestions by contacting us.If you are working as a System Administrator/Linux Admin/DevOps/SRE then most probably you will need to deal with performance-related issues in the Linux environment. We suggest trying the fully-functional 30-day trial to see how it works in your environment. PA Server Monitor downloads and installs quickly, and is easy to configure. The File & Directory monitor will work fine with one big caveat: If you are checking sub-directories there can't be recursive links because the difference between a link and child directory can't be determined from Windows.With Samba installed such that a Windows computer can access the remote disk:.The TCP Port monitor connects to a specified TCP port, and optionally sends a string of data and checks for an output string.Monitoring FTP servers works fine using the FTP Server monitor.The Mail Server monitor checks SMTP, POP3 and IMAP4 servers regardless of server operating system.Web Page monitoring can be done for web pages served from any HTTP server.Syslog events can be received from any device.SNMP Traps can be received from any device, filtered, alerted on, and reported on.Our MIB parser makes it simple to browse through the SNMP Direct SNMP monitoring can be applied to anything that supports SNMP.The Process monitor uses SNMP behind the scenes to verify the specified processes are running on Linux/Unix.SSH can be used in the Execute Script monitor to run arbitrary scripts on a device to check on and record statistics, indicate if alerts should be fired, etc.The Smart Config process will automatically create a bandwidth monitor if those SNMP objects are found. Bandwidth is monitored and charted using the standard SNMP monitor by watching ifInOctets and ifOutOctets.Reports and alerts are naturally supported too. Ping Response monitoring can be directed at anything with an IP address.It too will switch to SNMP in the background and display disk volumes for monitoring. Disk Space can be monitored with the standard Disk Space Monitor.When it detects that it's not communicating with a Windows server, it switches to SNMP in theīackground and simulates Windows CPU and memory counters. CPU & Memory can be monitored using the standard Performance Monitor. ![]() This is accomplished using standard protocols: PA Server Monitor has great support for monitoring Unix-based operating systems like Linux, and network devices like routers and firewalls.
