lost data resulting from system failure or incompetence As a responsible system administrator I want to ensure that our MongoDB databases are running as expected And that we have good slaves of the masters (well, secondaries to our primaries...) And that our snapshotted backups are up to date @critical Scenario Outline: Ensure MongoD is running When I SSH to <host> and run `pgrep mongod` Then it should exit successfully Examples: | host | | mongo-primary.int | | mongo-secondary.int | | mongo-secondary.int |
up and running the expected version When I open a socket to <host>:<port> and send "INFO\r\n" Then the output should include "redis_version:<version>" Examples: | host | port | version | | redis.int | 6379 | 2.4.2 | | redis-staging.int | 6379 | 2.4.2 |
