Monitor Redis downtime in your Objective-C application

We all know that Redis is a powerful in-memory data structure store, used as a database, cache, and message broker. Here at LogSnag, we commonly use Redis in our backend services to store it as our primary cache layer to improve the performance of our compute-intensive workloads.

However, just like any other service, Redis is not immune to downtime and outages. In fact, there are dozens of reasons why Redis can go down, including: network issues, hardware failures, and even human errors. In many cases, Redis downtime can be a critical issue causing degraded performance or even complete service outages. Resulting in a bad user experience or even loss of revenue.

Therefore, it is important to monitor Redis downtime in your application to ensure that your users are not affected by any downtime or outages. Fortunately, LogSnag makes it trivial to track such events and makes it easy for our team to monitor when Redis goes down.

With LogSnag, we can easily track the downtime of Redis and any other service in our application. The way we handle this is by watching the status of our Redis connection in our application. If the service is down, we instantly trigger an event to LogSnag. This allows our team to instantly be notified when Redis goes down and take the necessary steps to resolve the issue.

Setting up LogSnag

1. Sign up for a free LogSnag account.
2. Create your first project from the dashboard.
3. Head to settings and copy your API token.

Objective-C code snippets

To track your Redis downtime, you can use the following code snippet Please don't forget to replace the YOUR_API_TOKEN with your API token and update the project and channel names.

#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\":\"Redis is down\",\"description\":\"Redis has been down for the last 5 minutes\",\"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);
