Monitor when database goes down in your Objective-C application

LogSnag makes it easy to track your Objective-C application and monitor when your database goes down.

Almost every Objective-C application requires some data persistence. In a good number of cases, we can go by using a simple JSON, CSV, or even a text file to store our data. However, in most cases, we need a more robust solution that can handle a large amount of data and many requests and allow us to perform complex queries.

This is where databases come in. Databases are a great way to store and retrieve data in a structured form. They are also a great way to perform complex queries and scale our application. However, databases can be a complex topic and can be challenging to set up and maintain.

One of the most common problems with databases is that they can go down and become unavailable for various reasons. As a consequence, our Objective-C application will fail to work correctly and will not be able to retrieve or store data.

In such cases, it's essential to monitor your database activity and notify you and your team when something is wrong. This way, you can take immediate action and fix the problem before it becomes a significant issue.

Fortunately, LogSnag is an excellent tool for this problem as it trivializes tracking events in your Objective-C application and monitoring database outages. With LogSnag, you can easily track your database outages in real-time and notify you and your entire team when something goes wrong.

Objective-C code snippets

Use the following code snippet to track your database outages with LogSnag. Please don't forget to replace the YOUR_API_TOKEN with your API token and update the project and channel names.

Using Objective-C with NSURLSession
#import <Foundation/Foundation.h>

dispatch_semaphore_t sema = dispatch_semaphore_create(0);

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"https://api.logsnag.com/v1/log"]
  cachePolicy:NSURLRequestUseProtocolCachePolicy
  timeoutInterval:10.0];
NSDictionary *headers = @{
  @"Content-Type": @"application/json",
  @"Authorization": @"Bearer YOUR_API_TOKEN"
};

[request setAllHTTPHeaderFields:headers];
NSData *postData = [[NSData alloc] initWithData:[@"{\"project\":\"my-saas\",\"channel\":\"status\",\"event\":\"Database is Down\",\"description\":\"PostgresSQL is down in Oregon\",\"icon\":\"🚨\",\"notify\":true}" dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:postData];

[request setHTTPMethod:@"POST"];

NSURLSession *session = [NSURLSession sharedSession];
NSURLSessionDataTask *dataTask = [session dataTaskWithRequest:request
completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
  if (error) {
    NSLog(@"%@", error);
    dispatch_semaphore_signal(sema);
  } else {
    NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *) response;
    NSError *parseError = nil;
    NSDictionary *responseDictionary = [NSJSONSerialization JSONObjectWithData:data options:0 error:&parseError];
    NSLog(@"%@",responseDictionary);
    dispatch_semaphore_signal(sema);
  }
}];
[dataTask resume];
dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);
