I installed Zabbix Server 3.2 on Ubuntu 16.04 using a package. When I go to the Configuration tab, there is no Web Monitoring option. How do I activate that option?
Web monitoring is now part of host/template configuration, you can access it for each host/template. From the Zabbix 3.2 manual:
Since Zabbix 2.2 web scenarios are attached to hosts/templates in the
same way as items, triggers, etc.

I am trying to port one of our Tomcat based Windows application to Windows Nano Server Container. The installation process includes two Windows Service installations - an ActiveMQ service and another Tomcat Service. This is achieved using two batch files provided with the product. In addition to installing the service, they also pass several arguments pertaining to JVM. Now the issue I am facing is I am not able to get these services installed on a Nano Server. The same Dockerfile works perfect and installs the product on Windows Server Core Container.
Observation: The services which get installed through batch files are dependent on two system components - Ancillary Function Driver for Winsock (Service name: afd) and TCP/IP Protocol Driver (Service Name: tcpip). This is something which I discovered on a VM where the product was installed when checking the service properties. I see that they are absent in a Nano Server Container but are present in Windows Server Core container. Could that be a reason? If yes, is there any way to get those services running on Nano Server?
I am at a loss on how to troubleshoot this issue. Are there any limitations on Nano Server Container when it comes to Windows Services?
Consider building your docker container from the ground up,
Determine and set your prerequisites
Install all of the dependencies first
Install the application and services in question
(For additional information you can look at this wiki page.)
The Nano server container is minimal and misses many windows default services, you’ll have to build most of them through Dockerfile yourself.
The easiest method will be to do this manually on Nano server and confirm everything to be working in the docker container/image, and then later generate an automated build.
I need to use standard mysql, in plesk it says everywhere that it is mysql but when I login to console it says mariadb.
I understand that it is very similar but this plesk will be hosting staging systems so they must use exactly the technology that the product servers use.
Is it possible to do it somehow using the web interface or do I have to manually install it from console?
As I see it's impossible because plesk-mysql-server package has explicit dependency for mariadb-server.
Yes, you can solve this with --force, but it means further troubles with plesk updates and upgrades.
If you need DB server for some application you can install it on separate server and register it as remote DB server in Tool&Settings > Database Servers.
I am new in Apache Drill. I have gone through the Apache Drill official site and their documentation, but couldn't understand when to use Distribute system and when to use Embedded System.
I want to apply Drill in live project.So please give some advice which one to use (Embedded or Distributed) and how ?
Thanks in advance.
Embedded Mode: This requires less configuration & it is preferred for testing purpose.
As per drill docs:
Drill in embedded mode installs Drill locally on your machine. Embedded mode is a quick way to install and try Drill without having to perform any configuration tasks. A ZooKeeper installation is not required. Installing Drill in embedded mode configures the local Drillbit service to start automatically when you launch the Drill shell.
Distributed Mode: In this mode, drill runs on one or more nodes in a clustered environment. Running a ZooKeeper quorum is required.
As you asked, for live project you should use distributed mode. If you are using any hadoop cluster, you can install Drill on the same cluster. You need to install Drill on all the nodes. Check docs for more details.
Edit:
As you are new to Drill, for POC purpose you should use embedded mode.
Download Drill.
Start Drill with command bin/drill-embedded (for linux).
For windows check docs.
Add plugin through web UI
Start Querying.
I am new to IBM Worklight,and i found a way to connect to the MySQL using the SQL adapter.
the configuration as below:
<dataSourceDefinition>
<driverClass>com.mysql.jdbc.Driver</driverClass>
<url>jdbc:mysql://localhost:3306/worklight_training</url>
<user>Worklight</user>
<password>Worklight</password>
</dataSourceDefinition>
Since the adapter are compile together with the app, just wondering, is it safe? is there a possibility of someone decompiling my apk or ipa to view the adapter connection thus acquire the user and password to my mysql database.
A hacker decompiling your .apk or .ipa file will not find the database username/password there, for the simple reason that the adapter is not compiled "together with the app" and is not part of any artifacts that you install in a device.
An adapter is a server-side entity, not client-side.
The adapter is an object stored in the memory of the running application server.
Adapters are Server side code andare not part of the apk or ipa files.
You can check/confirm this information in Worklight documentation. The details about adapters, under "Developing the server side of a Worklight Application" are at:
http://www-01.ibm.com/support/knowledgecenter/SSZH4A_6.2.0/com.ibm.worklight.dev.doc/devref/c_overview_of_ibm_worklight_adap.html
You can also check the Server Side Development of MobileFirst Platform Getting Started Modules
https://developer.ibm.com/mobilefirstplatform/documentation/getting-started-6-3/server-side-development/
(MobileFirst Platform is the new name of Worklight)
In worklight, you usually have the application (apk/ipa) communicating with a server side component (the adapters) running in a worklight server. The adapters are used to communicate with backend systems (like a mysql server). There are a few different types of adapters to communicate with different types of backends (like sql, http and SAP)
Please, let us know what documentation/guide caused you the understanding that adapters are part of the client apk/ipa. If that is really stated in any documentation, it is wrong and must be corrected.
Edit:
To connect to a MySQL DB (no matter if it is a standalone MySQL or in XAMP, LAMP or whatever package) you can follow this geting started tutorial
https://developer.ibm.com/mobilefirstplatform/documentation/getting-started-6-3/server-side-development/sql-adapter-communicating-sql-database/
Also note that, if you are using MobileFirst Studio (previously Worklight Studio) downloaded for free from Developer Works you have a developer version of the WOrklight Server running inside Studio so that you can create and deploy adapters and use it during development as your server. But when you go to production you are required to purchase licenses of Worklight because you don't have the worklight server available for free.
So if you have Studio, you have the server available but only for development purposes.
From xampp control panel you can install Apache and MySQL as windows services.
What are the benefits or differences of running Apache and MySQL as windows services from running them without these services?
These processes as Windows Server's services, get started when windows is restarted, and can be monitored and be operated as any other windows service.
Look at the documentation
