Using the Monyog API

You can access the API by passing parameters to Monyog through its base URL.

For example, if Monyog is running on a system with IP, then the parameters need to be passed to:

You can use either of the HTTP methods GET and POST.

The Parameters

The parameters that you will need to pass are:

  • _object: This basically addresses the logical object in Monyog that you want to direct your request to.The only acceptable value is MONyogAPI.
  • _action: This specifies the part of the object specified above that you want to direct your request to. The acceptable values are:
    • Alerts
    • DataCollection
    • Sniffer
    • LongRunningQueries
    • LockedQueries
    • LongRunningQueryAction
    • AddServer
    • EditServer
    • RemoveServer
  • _value: The operation that you want to perform for the action specified in the _action field. Acceptable values include for:
    • Alerts, DataCollection, Sniffer, LongRunningQueries, LockedQueries: enable & disable
    • LongRunningQueryAction: notify, kill & notifyandkill
  • _user: It may be Monyog user, LDAP user or LDAP Group user. In case, no user is supplied, admin account is used by default.
  • _password: The password for the specified _user.
  • _server: Name of the servers separated by a comma(‘,’) for which the operation to be performed.
  • _tags: Name of the tag separated by a comma(‘,’) for which the operation to be performed for all the servers under the specified tag.

Besides, if server names/IDs (_server) and (_tag) are not specified then the specified action would be performed globally.

API's for server management:

To manage servers in Monyog via API, the following parameters need to be passed:

  • _server: The name of the server to be registered
  • _mysqlhost: MySQL host/ip address
  • _mysqluser: MySQL user name
  • _mysqlport: MySQL port
  • _mysqlpassword: MySQL user password

For example, to add a server:

curl  ""

Additional parameters for registering servers are listed  here.

For example, suppose you have a server named Production001 registered with Monyog. To stop data collection for this server using the HTTP GET method, the URL would look like:

curl “”

In summary, the various URLs that you can use with  curl:

  • Starts data collection for <server name>
curl ""
  • Starts data collection for <multiples servers>
curl ",Test"
  • Stops data collection for <server name>(Slave Of Production)
curl ""
  • Starts data collection for <tag>
curl ""
  • Stops data collection for <tag>
curl ""
  • Enables alerts for <server name>
curl ""
  • Disables alerts for <server name>
curl ""
  • Enables alerts for <tag>
curl ""
  • Disables alerts for <tag>
curl ""
  • Enables Sniffer for <server name>
curl ""
  • Disables Sniffer for <server name>
curl ""
  • Add Server
curl "http://localhost:5555/?_object=MONyogAPI&_action=addserver&_mysqluser=msandbox&_mysqlhost="
  • Add Server with SSH Tunnel
curl "http://localhost:5555/?_object=MONyogAPI&_action=addserver&_mysqluser=msandbox&_mysqlhost="
  • Edit Server
curl "http://localhost:5555/?_object=MONyogAPI&_action=editserver&_mysqluser=msandbox&_mysqlhost="
  • Delete Server
curl "http://localhost:5555/?_object=MONyogAPI&_action=removeserver&_server=Test"

Return Codes

Assuming that the connection to Monyog was successful, it will return a text message. The message will be in the JSON format:

{“STATUS”: “SUCCESS/FAILURE”, “RESPONSE” : “<Response text>”}

Your application can parse this message and determine whether the operation was successfully carried out or not.

NOTE: Since version 5.21 we have deprecated the API calls to "_object=ConnectionMgr". Instead use "_object=MONyogAPI".


The Monyog API is very flexible and can be accessed from other programming languages including scripting languages such as Perl, VBScript, etc.  Here is a very generic Perl script that accepts the required parameters from the command line and executes the specified action:

#! /usr/bin/perl
use LWP 5.64;
# USAGE: <hostname>:<port> <user> <password> <connection_name/ID> <action> <value>
# $ARGV[0] = hostname:port of server running Monyog
# $ARGV[1] = Monyog user
# $ARGV[2] = Monyog password
# $ARGV[3] = connection name
# $ARGV[4] = action
# $ARGV[5] = value
my $numArgs = $#ARGV + 1;
if($numArgs < 5) {
    die 'USAGE: <hostname>:<port> <user> <password> <connection_name/ID> <action>';
my $browser = LWP::UserAgent->new;
# The request URL
my $url = URI->new('http://' . $ARGV[0] . '/');
# The form data pairs:
    '_object' => 'MONyogAPI',
    '_action' => $ARGV[4],
    '_user' => $ARGV[1]
    '_password' => $ARGV[2],
    '_server' => $ARGV[3],
    '_value' => $ARGV[5]
# The response object
$response = $browser->post($url);
if (!$response->is_success) {# Error connecting to MONyog
    die $response->status_line . "\n";
  else { # Successfully connected to MONyog; print MONyog's response
    print $response->content . "\n";
