Question

I don't want to customize alert me in SharePoint like this link

But i want to get alerts properties like:

1. I want to know that Alerts defined on which list or Doc-Lib?
2. When they want (email or SMS?) (immediately or everyday they want to SharePoint send alerts)
3. Who define this alerts (which user)?
4. How many times this alerts fire in last days? (History)
5. Is there any way like event handlers in android we subscribe SharePoint event handlers and fire event or run custom code or call web service?

Case number 4 or 5 has lower priority : If impossible or hard or spend your time or out of scope of this question we skip that.

Answer 1

1. I want to know that Alerts defined on which list or Doc-Lib?
2. and When they want (email or SMS?) (immediately or everyday they want to SharePoint send alerts ?

you can achieve this via SQL query, where The Alerts in SharePoint have been stored in Content Database Specifically at ImmedSubscriptions and SchedSubscriptionsTable. based on When to Send Alert Option

Also, you can use SSOM via C# To get alerts via SPAlertCollection to return the collection of alerts for the Web site or user or list.

I wrote more details about The two methods and what's each field at ImmedSubscriptions and SchedSubscriptionsTable denote to with detail steps at Get All User Alerts By List Name in SharePoint 2013

3. Who define this alerts (which user)?

unfortunately , I can't find any info about the created by for alerts at this tables , only the user ID of the user who will receive alerts.

4. How many times this alerts fire in last days? (History)

Some information may be available at EventCache table but I am not sure but I Checked this article that describes in details some stored procedure and other tables related to alerts SharePoint E-Mail Confirmations and Alerts (under the hood)

Note : to achieve 3,4 you can also build your own custom simple alerts based on your requirement that will do the same functionality of build in alerts via workflow and event receiver (on item not on alerts it's not applicable ) to can track your notification in flexibility manner .

5. Is there any way like event handlers in android we subscribe SharePoint event handlers and fire event or run custom code or call web service?
