I am looking for a monitoring tool for CPU,MEMORY resources running under AZURE VM and Need Alerts also. We are not looking for paid solutions, but we would like to run a monitoring server. In our cloud, we will launch and remove servicesI wonder what tool is best to monitor hosts and services when they will be added/removed in a daily basis?
I am considering Ganglia, Nagios, Icinga and Sensu. Any other not paid option is welcome too as long as it can monitor the described scenario.

Is it possible to monitor or to get mails alerts while a pod in down? How to set the alert?
Yes, it possible you have to setup Prometheus with Alertmanager.
I recommend using prometheus-operato as an easier way to start with monitoring.
It depends if you want to use open source apps or you want to use paid software for monitoring and alerting.
As #FL3SH advised most used software to monitor and sending alerts is Prometheus and Alertmanager. This solution have many tutorials online "how to", for example this one.
However there are many other paid software to monitor your cluster/pods, alert you, create history diagrams etc. (like datadog, sysdig, Dynatrace) or mixed solutions (like Prometheus and Grafana, cAdvisor, Kibana, etc.) For more information you can check this article.
Please note that each cloud provider offers some specific monitoring features.
Has anyone tried connecting to IBM bluemix using bosh-cli. I am seeing performance issues in my requests and was going through this article on cloud foundry. I am planning to login to ssh to gorouter and monitor go-router CPU utilization.
Can someone recommend any way to capture the following metrics from Bluemix:
CPU utilization
Latency
Requests per second
what do you mean by "connecting to IBM bluemix using bosh-cli"?
When you think about the public available IBM Cloud (formerly Bluemix) that's represented here https://console.bluemix.net/ it's not possible. The bosh cli is to maintain the platform, thus Cloudfoundry and potentially other deployments but not your apps.
If you have a private installation you might check the metrics that the system provides. Infos here https://docs.cloudfoundry.org/running/all_metrics.html
When you want to have metrics about your app I could think off your app is providing these metrics. Or you put something in place like the New Relic monitoring. The have a bunch of application performance monitoring (APM). Info here https://docs.newrelic.com/docs/agents

We have a public website hosted on two Azure IaaS VMs which are behind a Network Load Balancer. What are the available solutions to auto patch and reboot without impacting site availability?
I am looking for a solution like this
Suppress the IaaS VM in NLB to stop the traffic coming to the VM. (apply a network security group to stop the traffic)
Run the monthly patches/updates on the IaaS VM
Restart the IaaS VM
Enable the IaaS VM in NLB to allow the traffic.
Move on to next server
Are there any solution available for this in Azure?
or
do we need to prepare our own PowerShell scripts to do this? if its a PowerShell script how to make it run monthly once?
Are there any solution available for this in Azure?
I suggest you could use Update Management solution in the Operations Management Suite, you can now configure an automated patching schedule for your Azure IaaS VMs.
There you can define a one time, a weekly or monthly schedule. The possibility adding different VMs to different schedules ensures that your services running on Azure IaaS VMs will be always available during an automated patching schedule.
More information please refer to this link.
If I've understood the docs properly, azure service fabric-based apps/microservices cannot be installed together with their service-fabric operational environment in one "packaged installer" step. For example, if I want to deploy a set of microservices on premises at a company that is running a typical windows server 2012 or VMWare IT center, then I'm out of luck? I'd have to require the company to first commit to (and execute) an installation of an azure app service fabric on several machines.
If this is the case, then the Azure Service Fabric is only an option for pure cloud operations where the service fabric cluster can be created on-demand by the provider or for companies that have already committed to azure service fabric. This means that a provider of classical "installer-based" software cannot evolve to the azure service fabric advantages since the datacenter policies of the potential customers is unknown.
What have I missed?
Yes, you always have to have a cluster to run Service Fabric Applications and Microservices. It is however not any more limited to a pure cloud environment, as of September last year the on-premise version of Azure Service Fabric for Windows Server went GA (https://azure.microsoft.com/en-us/blog/azure-service-fabric-for-windows-server-now-ga/) and that lets you run your own cluster on your own machines (whether physical or virtual, doesn't matter) or in another data center (or even at another cloud provider).
Of course, as you say, this requires your customer company to either have their own cluster or that you set one up for them (https://learn.microsoft.com/en-us/azure/service-fabric/service-fabric-cluster-creation-for-windows-server). They will also need to have the competence to manage that cluster over time. It could be argued though that this shouldn't be much more difficult than managing a VMWare farm or setting up and managing say a Docker container host(s).
For the traditional 'shrink-wrapped-DVD-installer-type' of software vendor this might not be as easy as just supplying an .exe and some system requirements, i agree with you on that. If the customer can't or don't wan't to run their own cluster and cloud is not an option then it definitely adds additional complexity to selling and delivering your solution.
The fact that you can run your own cluster on any Windows Server environment means that there is no real lock-in to Azure as a cloud platform, I think that this is a big pro for SF as a framework. Once you have a cluster to receive your applications then you can focus on developing that, this cannot be said of most other cloud-based PaaS frameworks/services.
Can you use mongodb and redis/memcached with azure?
I'm guessing no but just want to make sure.
It turns out they do support things other than .net, are they using linux servers then?
You can very easily run mongodb in Windows Azure. I presented this at MongoSV - video here.
EDIT: In December 2011, 10gen published their official MongoDB+Azure code on github. This contains a project for replica-sets, as well as a demo ASP.NET MVC application (taken from the Windows Azure Platform Training Kit) that uses a replica set for its storage.
Standalone servers are straightforward, except you have to deal with scale-out: you can't have multiple instances of a standalone server simultaneously, so you'll need to plan for this: take all but one out of the load balancer, or only launch mongod if you can acquire the Cloud Drive lock.
Replicasets are doable, as I demonstrated at MongoSV. However, I didn't cover the intricacies of graceful shutdown of a replicaset to ensure zero data loss.
You can run memcached as well - see David Aiken's post about this. Note: Now that the AppFabric Cache service is live, you should look into the pros/cons of using that over memcached. Cost-wise, AppFabric Cache should run much less, as you don't have to pay for role instances to host your cache. More info about AppFabric Cache here.
You now also have the option of running Redis in Windows Azure on Linux virtual machines ! In the case of Redis, this would allow you to use the "official" build instead of the "unsupported" Windows build ... For MongoDB, both choices seem equally valid (running on Linux virtual machines, "plain" Windows virtual machines, or using 10gen's package to run on "managed" VMs (Cloud Services).
FYI, there's now a Redis installer for Windows Azure available from MS Open Tech (my team). Here's a tutorial on how to use it: http://ossonazure.interoperabilitybridges.com/articles/how-to-deploy-redis-to-windows-azure-using-the-command-line-tool
[UPDATE] Azure now supports MongoDB and Redis.

In the Azure Store you can now select Redis Cloud as an add-on.
Heres the Azure store description:
"Redis Cloud is a fully-managed cloud service for hosting and running Redis in a highly-available and scalable manner, with predictable and stable top performance. Tell us how much memory you need and get started instantly with your new Redis database."
PUBLISHED DATE 3/31/2014
You can access the store by selecting the "New" button in the Azure portal then "Store". I have yet to use it but it looks promising.
Azure now has a first-party Redis service, currently in preview:
