After zimbra is installed on multiple servers, the Web Console displays a Red Cross for all services except the master server, indicating that the status is abnormal. However, when you use zmcontrol status to view the service status, the service is normal. This is because the logger server and corresponding port are not specified in the newly added server. You can solve this problem by editing the following configuration file. > VI/etc/rsyslog. conf A) Logger server (logger. Group) # Provides

To install a supervisor, you can directly use Yum install supervisord. However, the version may be earlier.

Loadrunner monitors the installation and operation of linux servers-Linux Enterprise applications-Linux server application information. The following is a detailed description. I used to find a lot of related materials. later, I checked some information about linux on the Internet and found out where the error was. the installation is successfully monitored through the experiment. so share it with you. 1. install two service packages: rsh and rsh-serv

Android Download Manager monitors progress anywhere You may want to monitor the progress anywhere in the application market or other downloads, and implement it well. It is relatively simple to share and prevent memory overflow. We use a weak reference to bind the View to update the progress method. Map > ViewListem = new HashMap > (); // Weak reference to the progress bar Prevent recovery when the memory is insufficient. Key is V

The Shell script monitors the running status of a specified process. This article mainly introduces how to monitor the running status of a specified process using Shell scripts. This article provides the script code directly. For more information, see In the previous blog, I wrote the implementation method of the automated testing program. Now developers need to know the process to be tested (here it refers to the main process running on LINUX) the ru

AngularJS monitors Scope variables and calls the Scope method externally. In AngularJS, you sometimes need to monitor a variable in the Scope, because the variable changes will affect the display of some interface elements. Sometimes, you also want to call a method of Scope through jQuery. For example: We hope that: ● Disable the jQBtnState variable value in Scope if it is set to false and the id is set to jQBtn.● Click the jQBtn button to call a met

Ctop: a command line artifact that monitors the performance of Linux containers Ctop is a new command line-based tool that can be used to monitor processes at the container level. By using the resource management function of the controller group (cgroup), containers provide a virtual environment at the operating system level. The tool collects data related to memory, CPU, block input and output, as well as the owner, boot time, and other metadata from
