Is it possible to create a rotation of on call personal with Zabbix.
What I want to archive is that emails with issues only go to a specific person during one week, and that change automatically when the we ends.
Thanks
That can not be done with the built-in capabilities. You would have to use external scripts as Zabbix alertscripts, or script things using the Zabbix API.
There is a feature request in Zabbix to do exactly this.
https://support.zabbix.com/browse/ZBXNEXT-537
Until then, you could take a look at "iLert" or "OpsGenie"

We are using Dynatrace to monitoring all our infrastructure and we want to monitor some specific files in our servers (I.Ex. /etc/passwd) , but there is no specific monitoring for that. The Dynatrace agent is running inside all our servers.
Does anyone know how to achieve this or has implemented some solution for this?
Thanks.
As per my understanding the answer would be a no. Dynatrace supports custom plugin in python and I have written few custom plugins but that are executed per min to send the metrics.
But I don't think so writing a custom plugin for this would be good use case.
For the triggers perspective you can go to the Settings "Anomaly Detection" and check if there is any option but quite sure there is no such option for this configuration.
You can raise an RFE for this -- this is actually a good requirement not from /etc/passwd perspective but from other stuff can be monitored.
Is there any way to track an external site with socket.io? So whenever the website changes then it would automatically send an event to my server?
For example:
socket.on("newconnectionfromxxxxxxxxxxxxxxx", function (websiteChange) { //websiteChange would be the contents of the updated website.
});
Sorry if this questions is obvious because I couldn't find anything online.
EDIT: The site that I want to be tracking is a JSON file.
socket.io works between two cooperating sites. So, it would only help you here if the site you want to monitor specifically supports an incoming socket.io connection AND it supports sending a notification message over that connection whenever the specific file you are interested in changes.
If the site you want to monitor does not have such specific monitoring features, then the best you could do is to regularly download the file of interest and see for yourself if it has changed.
Since all websites are not really fully event-driven/reactive at this time, you'll have to poll your website target periodically and look at that JSON file for differences. There are many "filewatcher" programs (C#, Java, etc) out there that hook into the native OS filesystem event mechanisms; you could alter one of these programs to trigger an WS or HTTP event to your server. There is a NodeJS wrapper that might be helpful for you: https://github.com/paulmillr/chokidar
Bummer the Unix "watch" utility didn't have an option to trigger events when a diff was detected instead of visually highlighting the change. It would be really cool if it has a "-difftrigger 'some-command'" option...
How can I set Observables to listen to different events from a bucket? So that whenever a new document added to the bucket or existing document updated I can read them and push it to the destination.
Note: Just getting started with couchbase.
Right now the SDK doesn't offer an API to listen to changes in the database. This is something that might be built as a facade on top of DCP, the protocol for cross data center replication, at a later point in time
To add more to what Simon said, you might be able to write your own DCP connector. DCP does provide the stream of changes you are looking for, but you have to have a connector that will ingest that stream. If this is something you might be up for, i'd look at the code for existing connectors like the Kafka connector and see if you could use them to create your own.
As Kirk said, you can definitely use DCP for this, as long as you're ok with writing it in Java, because that's the only SDK that currently has (experimental) support for streaming document changes.
As it happens, David Maier wrote a step-by-step tutorial on how to implement a change notification listener for Couchbase: http://nosqlgeek.blogspot.co.il/2015/05/dcp-magic.html
I would like to be able setup an Asterisk service where users can self register and create their own numbers. I was hoping to use extension contexts to achieve the actual partitioning of accounts. However the only way I can see to do this is by editing the extensions.conf file and manually restarting the service.
Does anybody have any suggestions on how to achieve this by using Realtime? I have seen various patches, etc but they are all very old and never made it into a stable release.
There is no any need in patches.
All that chnages in asterisk core since 1.4 version.

But that will not work very effective
Very likly you need hire expert who do it correctly via db lookups/dialplan.
I am creating a desktop app that will create some reports. I want to export these reports as RSS or ATOM feeds. I can easily create feeds with Rome lib for Java. But I have no idea how to spread them. I thought about embedding httpd into my app, but it's bad idea, because a computer can be behind NAT or turned off.
I need some kind of "proxy" server, where can I push my feeds, and clients will be able to pull content from that server.
I can probable write server side app fore this, but first I'd like to find out if some dedicated solution is available for problems like this.
I was also thinking about using some blogging platform and using its API. What do you think about this approach?
One more thing I have to consider when choosing platform ability to handle lot of updates. Sometimes desktop app will be shut down but when it will be running, it generates quite a lot of updates.
Check out Google's feedburner.
EDIT
Here's a better link for their help / faq. You'll still need to use some service to generate your feed, but it won't have to handle a heavy load. Feedburner will poll your feed every 30 minutes and their servers will act as a proxy for your feed. As far as how to publish the feed for Feedburner to read, I would recommend writing a service to handle this, even more considering that you getting the data for the feeds from a number of desktop applications, and it'll probably be easier to write a custom service to interface with them, store your data in a DB, and publish feeds than it would be to try and modify a blogging service for this purpose.
I don't know why I didn't think of this when I first answered your question, but Yahoo has a service called Yahoo Pipes which allows you could use to generate feeds from various kinds of inputs. I'm not sure how well it would scale but it might work for you.
