System Configuration Reference

This is a reference for the system configuration file located at $MOOGSOFT_HOME/config/system.conf. It contains the following sections and properties:

Message Bus (MooMs)

connections_per_producer_pool

The number of connections to use for each message sender pool. For example, if a message sender pool has 20 channels and this property is set to 2, the channels are split across both connections so that each has 10 channels. To configure this property, you must manually add it to the mooms section.

Type

Integer

Required

No

Default

2

zone

Name of the zone.

Type

String

Required

No

Default

N/A

brokers

Hostname and port number of the RabbitMQ broker.

Type

Array

Required

No

Default

"host" : "localhost", "port" : 5672

username

Username of the RabbitMQ user. This needs to match the RabbitMQ broker configuration. If commented out, it uses the default "guest" user.

Type

String

Required

No

Default

guest

password

Password for the RabbitMQ user. You can choose to either have a password or an encrypted password, you cannot use both.

Type

String

Required

Yes. If you are not using encrypted password.

Default

guest

encrypted_password

Encrypted password for the RabbitMQ user. You can choose to either have a password or an encrypted password, you cannot use both. See Moog Encryptor if you want to encrypt your password.

Type

String

Required

Yes. If you are not using password.

Default

N/A

threads

Number of threads a process can create in order to consume the messages from the Message Bus. If not specified, the thread limit = (Number of processors x 2) + 1. Altering this limit affects the performance of Moogsoft AIOps processes such as Moogfarmd and Moogpoller.

If your logs indicate an issue in creating threads, Moogsoft advises that you increase the ulimit, the maximum number of file descriptors each process can use, for the Moogsoft AIOps user. You can set this limit in /etc/security/limits.conf.

Type

Integer

Required

No

Default

10

message_persistance

Controls whether RabbitMQ persists important messages. Message queues are durable by default and data is replicated between nodes in High Availability mode. Setting this value to false means that replicated data is not stored to disk.

Type

Boolean

Required

No

Default

true

message_prefetch

Controls how many messages a process can take from the Message Bus and store in memory as a buffer for processing. This configuration allows processes to regulate message consumption which can ease backlog and memory consumption issues. The higher the number, the more messages held in the process's memory. Set to 0 for unlimited processing. To achieve high availability of messages and ensure messages are processed, the value of this should be higher than 0.

Type

Integer

Required

No

Default

0

max_retries

Maximum number of attempts to resend a message that failed to send. Moogsoft AIOps only attempts a retry when there is a network outage or if cache_on_failure is enabled.

You can use this in conjunction with the retry_interval property. For example, a combination of 100 maximum retries and 200 milliseconds for retry interval leads to a total of 20 seconds. The combined default value for these properties was chosen to handle the typical time for a broker failover in a clustered environment.

Type

Integer

Required

No

Default

100

retry_interval

Maximum length of time to wait in milliseconds between each attempt to retry and send a message that failed to send.

You can use this in conjunction with the max_retries property. The combined value for these properties was chosen to handle the typical time for broker failover in a clustered environment.

Type

Integer

Required

No

Default

200

cache_on_failure

Controls whether Moogsoft AIOps caches the message internally and resends it if there is an initial retry failure. The system attempts to resend any cached messages in the order they were cached until the time-to-live value, defined by the cache_ttl property, is reached.

Type

Boolean

Required

No

Default

false

cache_ttl

Length of time in seconds that Moogsoft AIOps keeps cached messages in the cache list before discarding them. If a message is not successfully resent within this timeframe it is still discarded.

This defaults to 900 seconds (15 minutes). Increasing this value has a direct impact on sender process memory.

Type

Integer

Required

No

Default

900

confirmation_timeout

Length of time in milliseconds to wait for the Message Bus to confirm that a broker has received a message. Moogsoft does not advise changing this value.

Required

No

Default
