Collector configuration – dynatrace 6.3 – dynatrace community last linux kernel

Collector configuration – dynatrace 6.3 – dynatrace community last linux kernel • Before 6.2 Collector sizing mainly happened through adding more Collectors when the number of Agents per standard-Collector (2GB JVM heap) became too big. Linux kernel source download In some cases heap memory needed to be increased to 3 or 4GB. As of 6.2 the number of Collectors is no longer the pretty much exclusive sizing factor, but also JVM heap memory and the number of cores (and naturally disk space) available to a Collector process determines the number of Agents it can take. And: The Collectors will need a lot more heap and disk space (for class cache and inheritance map) if the instrumented applications are different, so applications should be hooked to Collector groups according to their


similarity. Newest linux kernel Sensible grouping of apps and equally sized Collectors in a group are also prerequisite for Collector – Agent load balancing. You should have gotten a proper sizing before you bought Dynatrace.

Please refer to the Collector Guidelines to adjust settings when your requirements change or ask sales or support. *NIX: Some Linux flavors come with low limits for the maximum number of files / sockets and processes / threads per user. Linux kernel module programming tutorial (1024) This normally poses no problem for the Dynatrace Collector, but if you run half a dozen of them within one user context and a couple of dozen Agents connected to each Collector you will need to raise both settings. Some Linuxes have limits of 64k, so increase low limits generously to (500 + 3 * numberOfAgentsConnected) * Collectors and be on the safe side for all eventualities.

Linux kernel development 3rd edition pdf (a lot of Agent Groups,…) Check limits before setting (them too low / lower than they were and trashing your system)! Check hard limits (and set them) to account for desired soft limits, as soft cannot exceed hard!

(permissions required!) Set limits permanently / for daemons in /etc/security/limits.conf. Linux kernel v2 See explanation there.

You could force a check for 2048 at Collector-startup with the -openfiles parameter, but there is not much point to it when several run under the same user. • *NIX: For the installation process you need Java Runtime Environment (JRE) 1.6 or later. • The installation for Windows and Linux includes a private JRE (1.8 as of Dynatrace 6.3) for runtime. The UNIX installer does not include the JRE, so go for a JRE 1. Linux kernel book 8 already for installation, as JRE 1.6 will not suffice for Collector runtime.

• *NIX: As of 6.3 reworked init.d shell scripts allow for Collectors (and the Server) to be started as non-root / under the desired user account.

If your Linux uses systemd for startup, please check out the attached systemd script samples! (wrappers for init.d) • Windows x86/x64 10/8.1/8/7/Vista or Server 2008/2012 with latest service pack Compatible JVMs for Collector runtime: Oracle (Sun) JVM 1.8+ (included with Windows and Linux installers), IBM JVM 1.8+, HP JVM 1.8+ Installation Windows Download the full Windows installation package for your architecture.

Download linux kernel source code Do a custom installation if you only need the Collector. The setup defaults to an installation path (%DT_HOME%) of %ProgramFiles%\dynaTrace\dynaTrace 6.3. Linux kernel repository (revision removed as of 6.2) The installation process creates Start menu entries and registers an auto-starting Windows service, configured to connect to a Dynatrace Server on the same machine (localhost) on the default port (6698 or 6699 (SSL)) and name (Dynatrace Collector 6.3). Linux kernel source code For other configurations see below. Linux kernel development tutorial Linux and UNIX You should use a designated account and best already run the installation in that user context.

As of 6.3 to that end you just have to define DT_RUNASUSER in the script. The Linux Collector installation file is named dynatrace-collector--linux-x86.jar, implying 32 bit on the x86 platform if you look at the other namings, but contains both bitnesses. On Linux, the installer prompts for bitness (32-bit or 64-bit) and for the installation directory, which defaults to /dynatrace-collector-6.3 . Linux kernel development 3rd edition (revision removed as of 6.2) This path is referred to as $DT_HOME. When you install on Solaris, HP-UX, AIX, z/Linux, or z/OS, the installer additionally prompts you for JAVA_HOME, which specifies the Java installation that is used to run the Dynatrace Collector. Linux kernel meaning The Linux version comes with a private JVM. Suggested installation is in /opt. Linux kernel contributors Start the installation by issuing: Define DT_RUNASUSER in the script (and other variables like DT_OPTARGS and DT_INSTANCE if necessary). Add this script to the system boot by using chkconfig –add dynaTraceCollector or, depending on your distribution, e.g. Update linux kernel on Debian (Ubuntu,…) use If you didn’t specify a DT_RUNASUSER, registered the script and restarted, then Collector was started as root and e.g. Linux kernel source /collector/osgi and temp will belong to root. Define linux kernel To correct this, run the above chown again! Check if dtcollector runs – and under what user with ps -eo pid,fname,user|grep dtcollec. Linux kernel tuning (uses 8-char file name, lists launcher) If this doesn’t work on your Linux flavor, try ps aux|grep dtcollector. Latest linux kernel version The first, short output is for the launcher and the second, long one is for the Collector. Latest linux kernel version (The third one is for grep.) The user the Collector runs under is at the very beginning, before the PID. Version kernel linux Configuration General Architectural Remarks Installation takes care of Dynatrace components and their configuration for basic local usage / small implementations. How to build linux kernel You may have just everything (all Dynatrace and your components) on one machine and use the stand-alone Collector service / daemon or even the Dynatrace Server-embedded Collector for a still smaller memory footprint. Linux kernel understanding (see Embedded Collector Usage Restrictions) With more complex, larger deployments you may need quite a number of Collectors. Linux kernel config Depending on the architecture of your application the Collectors may be on one or more (virtual) machines. If you run the Collector on a different machine than the Dynatrace Server you must reference the Server in the registration (Windows) or in the *NIX shell script. Linux kernel location (see Configure a Collector Other Than Localhost) If you want to run more than one Collector on a machine you must create extra instances of the installed default instance as explained below. Linux network kernel (take care of Collector names and unique ports they listen for Agents) Once a Collector is up and connected to the Dynatrace Server, some parameters can be changed or additional ones can be set (e.g. Linux kernel programming language importantly: Collector Group) in the Dynatrace Client > Settings menu > Dynatrace Server… Linux kernel file > Collector vertical tab > Configuration (lower right) when you select a Collector in the upper pane. Linux kernel programming Configure a Collector Other Than Localhost The parameters set below can later on be reconfigured (e.g. Linux kernel bug Collector Group) in the Dynatrace Client > Settings menu > Dynatrace Server… How to check linux kernel version > Collector vertical tab > Configuration (lower right) when you select a Collector. O reilly linux kernel Windows • Unregister the service that was registered by default at install-time: • General syntax to register the Collector to connect to a Dynatrace Server on a different machine: %DT_HOME%/dtcollector -service install -server [:PortToConnectToServer] [-listen:PortToListenForAgents] Example: Register Collector that will connect to a Dynatrace Server / host named myDynatraceServer on the default port and listens for Agents on the default port. %DT_HOME%/dtcollector -service install -server myDynatraceServer The registration parameters are reflected in %DT_HOME%/collector/conf/collector.config.xml. Linux kernel latest Linux and UNIX On *NIX there is no automatic registration at install time, so you need not unregister a daemon initially, but to connect to a Dynatrace Server on a different machine you must at least set OPT_ARGS= (e.g. Actualizar kernel linux OPT_ARGS=”-server myDynatraceServer”) in the $DT_HOME/init.d/dynaTraceCollector shell script, Save As in /etc/init.d and register the daemon for boot with chkconfig (or the equivalent for it on your distibution). The Collector names (Windows: service names) and the port each Collector listens for Agents must be unique. If you want your Collector instance to connect to a specific Server other than localhost, add -server to the registration (Windows) or shell script (Linux/UNIX). The first start of the new Collector instance creates the directory structure \collector\instances\ that replicates the structure of the default instance and copies the files from there. El kernel de linux Extra Instances on Windows This example code shows how to register and start a new service called Dynatrace Collector 6.3 (MyCollector) (revision removed as of 6.2) that listens for Agent connections on port 9997: To start the collector02 instance at system startup, copy the $DT_HOME/init.d/dynaTraceCollector shell script, for example using Save As to create the flle . Linux kernel jobs /etc/init.d/dynaTraceCollector02. What is kernel in linux Make the following minimum changes: Be sure the in DT_INSTANCE and DT_OPTARGS=”-instance ” are the same. Add the script to the startup items by using /sbin/chkconfig –-add dynaTraceCollector02 (or the chkconfig equivalent on your distribution). Check for running Collectors by using ps ax | grep dtcollector. Linux kernel nedir Embedded Collector Usage Restrictions The Dynatrace Server includes an embedded (as opposed to stand-alone) Collector that should only be used for testing purposes. Linux kernel maintainers The embedded Collector is started in-process with the Server, a stand-alone Collector service / daemon must be explicitly started. Enable the embedded Collector via Settings > Dynatrace Server > Services > Allow Agent Connections to Dynatrace Server . How does the linux kernel work A Dynatrace Server restart is required after this setting is changed. The table indicates whether the embedded Collector can or cannot be used by different Dynatrace editions in different (license) scenarios. The executables and the main configuration file dtcollector.ini. Before starting the Dynatrace Collector, adjust the memory settings in the main configuration file dtcollector.ini. Which linux kernel Depending on your sizing, you may need to change the default values for the options -Xmx, -XX:MaxPermSize and -XX:PermSize in the configuration file to a reasonable size. Linux kernel process For detailed sizing recommendations, see the Deployment Guide. The following code example shows these switches added to the file: lines 3, 4, 5, and 6. The -XX:+UseCompressedOops option will be automatically appended by the 64-bit installer. Linux kernel tree This switch is not applicable for HP JVMs. How to build linux kernel from source JRE on Solaris, HP-UX, AIX, z/Linux, z/OS If you install the Collector on HP-UX, AIX, z/Linux, or z/OS, set the Java used to run the Dynatrace Collector. Linux kernel types In the dtcollector.ini file, revise the line after -vm to point to the Java executable of the desired JRE. Linux kernel development 3rd edition pdf For example: -vm /usr/java/jre1.8.0_51/bin/java Collector Placement Close to Agents A Collector should always be placed “close” (in terms of latency) to the connected Agents, as there are start-up ro
und-trips between them in the thousands – to instrument application classes,… El kernel de linux A Collector should be placed in the same sub-net / at least in the same data center as the Agents / instrumented applications, then connecting to the Dynatrace Server over the WAN, if needed. Kernel linux download Collector Fail-Over / Agent Connection Balancing See Collectors > Collector Groups for Connection-Balancing and Fail-Over for details. Linux kernel development by robert love Starting and Stopping dTCollector Arguments On Windows, you can control the Dynatrace Collector via the Start menu, command line, or Services control panel. Kernel linux ubuntu The registered service name is Dynatrace Collector [()]. To start or stop more than one Collector instance on one machine, see Extra Instances on Windows, above. Linux network kernel Starting and Stopping on Linux and UNIX For testing purposes, you can interactively start the Dynatrace Collector in the background ( -bg) by using the launcher dtcollector. Linux kernel upgrade The following commands start a Collector that listens on localhost for Agents on default port 9998 and connects to a Dynatrace Server via default port 6698: You can use /init.d/dynaTraceCollector start | stop | status to stop or check the Collector without caring about its pid. For normal operations, you should use the /init.d/dynaTraceCollector script that starts the Collector on the desired run levels at boot time. Linux kernel update without reboot For Linux, you can use the script without changes: Copy it to /etc/init.d and add it to boot time with chkconfig –add dynaTraceCollector. To detect any running Dynatrace Collector instance, the init script checks for a file dtcollector.pid located in /var/run. If an instance name is being used, the corresponding .pid file is called: /var/run/dtcollector..pid. Linux kernel version list If the .pid file is not present for some reason (e.g. Linux kernel path missing write permissions to /var/run ), the script tries to find the process ID by grepping the ps output for running dtcollector instances. Linux kernel developer jobs You may need to change ps and grep arguments to get the right Collector instance, which might be tricky when an instance name is being used. Linux kernel entry point Therefore, it is strongly recommended to configure the system so that .pid files can be used. Linux kernel name Troubleshooting Collector Load One particular scenario might overload the Collector: If you collectively restart your IIS instances, you should not have more than 50 Web Server Agents (depending on configuration) connected to one Collector. Linux kernel development 3rd edition pdf With normal operations, you may be able to connect more Web Server Agents to the same Collector. How to get linux kernel version Slow Application Startup If you experience high application startup time, chances are that the network latency between the Agents and the Collector they connect to is too high and the number of round-trips add up. Linux kernel version history Move the Collector “closer” to its Agents, avoiding e.g. Linux kernel source firewalls in between if possible, or at least use a very fast one. Linux kernel developers Collector Class Cache and Inheritance Map Sizes Do not underestimate Collector class cache and inheritance map sizes! Despite recurrent automatic cleanup (by default every week), they can get quite big quickly. You can set cleanup recurrence with (maximum age in milliseconds; below: one day): It appears that when using Collector instances, the DT_OPTARGS does not need to be specified, as the -instance parameter is specified anyways using the DT_INSTANCE variable value. Linux kernel process In fact, if you do specify the DT_OPTARGS with the suggested “-instance ” text, a syntax error is created in the startup script.
