I'm newbie to ambari,so I'm reading some articles about it
in one of these articles it's said that :
ambari dashboard is used to give information issued from Ganglia and Nagios
so I wonder if ambari use, or based on Nagios to monitor it's services, if not does it possible to use nagios to monitor ambari (and it's services ) ?
Nagios and Ganglia were used as standalone services, to provide info for Ambari 1.7.0 and less. Since version 2.0, Ambari moved to use his own monitoring service Ambari Metrics and Ambari Alerts. Support of Nagios with Ganglia was dropped.

I am using the released version on thingsboard github https://github.com/thingsboard/thingsboard/tree/master/docker
I tried using HAproxy ip but it doesn't seem to work. Anyone know which ip and port i should use?
RESOLVED
this version: https://github.com/thingsboard/thingsboard/tree/master/docker not have the transport configurations and logback.xml.
Is JIRA supported in GCE? If so, how to make it work?
We have installed 64-bit .bin of JIRA(6.4.1), and opened necessary custom http ports under Networks.
Started JIRA as service, but unable to see it work via browser. No error message than, timed out error!
Any help would be highly appreciated.
Note: We are new to Google Cloud Platform.
Did you enable the http and https services on your instance ? By default the GCE instance does not allow Http and Https traffic, you have to do it manually.
The Jira configuration for Google Compute Engine can be tricky. You need to make sure that:
The firewall rules under Netowrking allows a connection to Jira HTTP port or the HTTP enables in VM properties
The global Networking rules allow TCP traffic on this port
The virtual network have routes configured
If you use Apache as proxy for Jira (recommended) then make sure Apache is configured to point to the Tomcat port
Your Tomcat is configured
You have enabled port allocation using setcap utility
Your local machine firewall enables the connection (in Red Hat ipconfig is enabled by default and blocks the connections)
As you can see it may be tricky to install Jira on Google Cloud. It may be a good idea to use a deployment service like Deploy4Me to do this quickly and automatically.
Is it possible to monitor TITAN cassandra server with rexster remotely via JMX using something like VisualVM?
I have titan installed on the cloud and want to monitor it from my dev box. Is this possible.
I have read this
https://github.com/tinkerpop/rexster/wiki/Monitoring
but it seems that JMX MBeans are only available locally however I could be wrong
You can monitor Rexster JMX remotely with VisualVM, but it takes a bit of configuration and changes to rexster.sh as you need to include these environment variables:
-Dcom.sun.management.jmxremote.port=3333
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
You can read some more about how to do remote setup on the VisualVM site.
You mentioned that you are trying to monitor an instance in the cloud. You didn't mention the cloud provider, but I've had trouble doing this with EC2 in the past. Perhaps this post will help you out. While I've had issues with VisualVM remoting to EC2, I have successfully connected to Rexster via VisualVM from another EC2 instance without trouble so if all else fails that could be your workaround.
I have a Nagios Core 3.x setup and A linux-based appliance that has the capability to send SNMP alerts to a server.
How can I use my Nagios to leverage its snmp monitoring capabilities ???
You should read their documentation here
Nagios provides management of SNMP traps - including the ability to
read, process, and generate alerts from SNMP traps it receives. Nagios
can also send SNMP traps to other management hosts, which allows
seamless integration with other Network Management Systems.
I've used SNMPtt with Nagios with great success. You can install it with Nagios using these instructions: http://www.snmptt.org/docs/snmptt.shtml#Nagios-Netsaint
I am making one rails application which is integreted with RabbiMQ.
I want to integrate Fuse ESB in my application, but still after google I am not confirmed that RabbitMQ supports to Fuse ESB or not.
Can anybody tell me that RabbitMQ supports Fuse ESB or not?
FUSE ESB contains a messaging infrastructure based on the JMS technology of Apache ActiveMQ. ActiveMQ is not interoperable out-of-the-box with AMQP systems like RabbitMQ.
However, Apache Camel (also part of FUSE) supports AMQP via the client API of the Apache Qpid project. Since both Qpid and RabbitMQ implement the AMQP messaging standard, you may be able to communicate with a RabbitMQ broker from a Qpid client. There are some potential issues and solutions associated with this approach outlined here.
