modprobe is a Linux program originally written by Rusty Russell and used to add a loadable kernel module to the Linux kernel or to remove a loadable kernel module from the kernel. It is commonly used indirectly: udev relies upon modprobe to load drivers for automatically detected hardware. Nov 07, 2012 · PSI-Probe is an extended Tomcat manager. This post outlines how to place it behind CAS and specify permissions based on an LDAP attribute. The method outlined in this post has been adapted from documentation from Jasig on Tomcat Container Authentication, written by Marvin S. Addison. Aug 18, 2014 · PRTG Network Monitor already offers a set of native sensors for Linux monitoring without the need for a probe running directly under Linux. These sensors gather monitoring data via SNMP (Simple Network Management Protocol), SSH (Secure Shell), or WBEM (Web-Based Enterprise Management) and run on the Local Probe or the Remote Probe of a Windows system located in your network. ./perf probe --del='schedule*' Add probes at zfree() function on /bin/zsh ./perf probe -x /bin/zsh zfree or ./perf probe /bin/zsh zfree Add probes at malloc() function on libc ./perf probe -x /lib/ malloc or ./perf probe /lib/ malloc Add a uprobe to a target process running in a different mount namespace ./perf probe --target PRTG uses customized Linux and Unix sensors to monitor Linux systems, without the need to install or modify anything on the target device. Linux operating systems are monitored by way of SNMP and SSH protocols, while Linux servers are monitored using WBEM and SSH protocols. With SSH, data is sent via a secure connection to prevent sensitive May 11, 2020 · The reason for DNS_PROBE_FINISHED_NXDOMAIN is typically due to a misconfiguration or problem with your DNS. DNS is short for Domain Name System, which helps direct traffic on the internet by connecting domain names with actual web servers.

If a probe handler hits a probe, that second probe's handlers won't be run in that instance, and the kprobe.nmissed member of the second probe will be incremented. As of Linux v2.6.15-rc1, multiple handlers (or multiple instances of the same handler) may run concurrently on different CPUs.

Tutorial - Load balance Linux virtual machines in Azure The following example creates a TCP probe. You can also create custom HTTP probes for more fine grained health checks. When using a custom HTTP probe, you must create the health check page, such as healthcheck.js. The probe must return an HTTP 200 … Uprobe-tracer: Uprobe-based Event Tracing — The Linux (\*1) only for return probe. (\*2) this is useful for fetching a field of data structures. (\*3) Unlike kprobe event, "u" prefix will just be ignored, becuse uprobe events can access only user-space memory.
