Note that because criticals are always checked first, setting the warning equal to the critical is an effective way to turn warnings off and always give a critical.
The current supported actions are: The minimum version to use this action is Postgres 8. The --warning and --critical options are simply the number of. Usually, these values should be low, turning on the archive mechanism, we usually want it to archive WAL files as fast as possible. This action will only work for databases version 8.
The --warning and --critical options should be expressed as percentages. Databases can be filtered by use of the --include and --exclude options.

All databases which have the percentage from the first line are reported on the fourth line, separated by a pipe symbol. The --warning and --critical options can take one of three forms. First, a simple number can be given, which represents the number of connections at which the alert will be given. Second, the percentage of available connections can be given.

You can also filter the databases by use of the --include and --exclude options. To view only non-idle processes, you can use the --noidle argument. Note that the user you are connecting as must be a superuser for this to work properly. Give a warning when the number of connections on host quirm reachesand a critical if it reaches Give a warning when there are only 10 more connection slots left on host plasmid, and a critical when we have only 5 left.
Connect as port on the first two hosts, and as port on the third one. We want to always throw a critical when we reach 30 or more connections.
If more than one database has been queried, the one with the highest number of connections is output. Bloat is generally the amount of dead unused space taken up in a table or index.
The --include and --exclude options can be used to filter out which tables to look at. The --warning and --critical options can be specified as sizes, percents, or both. Valid size units are bytes, kilobytes, megabytes, gigabytes, terabytes, exabytes, petabytes, and zettabytes. You can abbreviate all of those with the first letter. Items without units are assumed to be 'bytes'. The default values are '1 GB' and '5 GB'. The value represents the number of "wasted bytes", or the difference between what is actually used by the table and index, and what we compute that it should be.
Note that this action has two hard-coded values to avoid false alarms on smaller relations. Tables must have at least 10 pages, and indexes at least 15, before they can be considered by this test. These values are ignored if either --exclude or --include is used. Only the top 10 most bloated relations are shown. You can change this number by using the --perflimit option to set your own limit.
Please note that the values computed by this action are not precise, and should be used as a guideline only. Great effort was made to estimate the correct size of a table, but in the end it is only an estimate. The correct index size is even more of a guess than the correct table size, but both should give a rough idea of how bloated things are.
The fourth line gives the database name, table name, and index name information.
This must run on the same server as the database that is being checked e. This check is meant to run on a "warm standby" server that is actively processing shipped WAL files, and is meant to check that your warm standby is truly 'warm'. It is also possible to use the special options --assume-prod or --assume-standby-mode, if the mode found is not the one expected, a CRITICAL is emitted.
At least one warning or critical argument must be set. This action requires the Date:: For MRTG or simple output, returns the number of seconds. Either the --warning or the --critical option should be given, but not both. The value of each one is the cluster identifier, an integer value. Make sure the cluster is the same and warn if not, using the result from above. A identifier must be provided as the --mrtg argument. The new default value is 64 KB.
A small stack reduces virtual memory usage and also saves CPU ressources.

A too small value will probably crash your Nagios process, though. You have been warned In order to avoid being hung by broken clients, Livestatus imposes a limit on the time for reading the query from the client. A value of 0 disables the timeout. Livestatus is waiting at most that much time for the next query.
If you add this paramter, then Livestatus will provide information about which host has inventory data and also gives access to that data in form of a couple of additional columns. Possible values are utf8, latin1 and mixed. Here is an example of how to add parameters: Using Livestatus Once your Livestatus module is setup and running, you can use its unix socket for retrieving live status data. Every relevant programming language on Linux has a way to open such a socket.
We will show how to access the socket with the shell and with Python. Other programming languages are left as an exercise to the reader. Accessing Livestatus with the shell A unix socket is very similar to a named pipe, but has two important differences: You can both read and write to and from it while a pipe is unidirectional. You cannot access it with echo or cat. Livestatus ships with a small utility called unixcat which can communicate over a unix socket.Privacy, Security, Society - Computer Science for Business Leaders 2016
