Understanding the transpose function: t()

Overview The transpose function is one of Bosun's more powerful functions, but it also takes effort to understand. It is powerful because it lets us alert at different levels than the tag structure of the underlying data. Transpose changes the scope of your alert. This lets you scope things into l...

Finding the Shortest Path from Source to other Nodes

Breadth-first-search (BFS) is an algorithm for traversing or searching tree or graph data structures. It starts at the tree root (or some arbitrary node of a graph, sometimes referred to as a 'search key') and explores the neighbor nodes first, before moving to the next level neighbors. BFS was inve...

Const Correct Function Parameters

In a const-correct function, all passed-by-reference parameters are marked as const unless the function directly or indirectly modifies them, preventing the programmer from inadvertently changing something they didn't mean to change. This allows the function to take both const and non-cv-qualified ...

Master - Slave Replication Setup

Consider 2 MySQL Servers for replication setup, one is a Master and the other is a Slave. We are going to configure the Master that it should keep a log of every action performed on it. We are going to configure the Slave server that it should look at the log on the Master and whenever changes happ...

Replication Errors

Whenever there is an error while running a query on the slave, MySQL stop replication automatically to identify the problem and fix it. This mainly because an event caused a duplicate key or a row was not found and it cannot be updated or deleted. You can skip such errors, even if this is not recomm...
