Hi We're planning to use collectd in a large project and wanted to know answers to some questions. Could anyone people please throw some light on these:
1. Does collectd have plugins to monitor the following NoSQL DBs: Cassandra, MongoDB, Redis, PostGreSQL? If yes, are they stable? (I mean not undergoing development) 2. In which programming languages can I write plugins for additional DBs that are not supported by collectd? 3. What is the minimum frequency of metric collection in collectd? 4. What's the format of data communication collectd uses to store/interact with other DBs/systems? (like JSON, XML, etc.) 5. Is there a limit to the maximum number of nodes that collectd can monitor? If yes, how much? 6. What is the approximate worst-case latency in collectd? 7. Does collectd provide any metric aggregation capability? (i.e. to perform functions such as sum, average, median, etc. on different metrics) I really need these answers but couldn't find them on the web. It will be great if you guys could answer most of them if not all. Thanks!
