Using logstash 7.13
We are running logstash on linux server which has _4 cpu(s) 15gb of ram of 100gb of ssd._ We are using persistent queue settings in logstash but we actually can't sure is this right configuration or can it be improve.
**logstash.yml** file
```auto
# ------------ Queuing Settings --------------
#
# Internal queuing model, "memory" for legacy in-memory based queuing and
# "persisted" for disk-based acked queueing. Defaults is memory
#
queue.type: persisted
#
# If using queue.type: persisted, the directory path where the data files will be stored.
# Default is path.data/queue
#
path.queue: /var/lib/logstash/data_queue
#
# If using queue.type: persisted, the page data files size. The queue data consists of
# append-only data files separated into pages. Default is 64mb
#
#queue.page_capacity: 64mb
#
# If using queue.type: persisted, the maximum number of unread events in the queue.
# Default is 0 (unlimited)
#
# queue.max_events: 0
#
# If using queue.type: persisted, the total capacity of the queue in number of bytes.
# If you would like more unacked events to be buffered in Logstash, you can increase the
# capacity using this setting. Please make sure your disk drive has capacity greater than
# the size specified here. If both max_bytes and max_events are specified, Logstash will pick
# whichever criteria is reached first
# Default is 1024mb or 1gb
#
#queue.max_bytes: 1024mb
#
# If using queue.type: persisted, the maximum number of acked events before forcing a checkpoint
# Default is 1024, 0 for unlimited
#
# queue.checkpoint.acks: 1024
#
# If using queue.type: persisted, the maximum number of written events before forcing a checkpoint
# Default is 1024, 0 for unlimited
#
# queue.checkpoint.writes: 1024
#
# If using queue.type: persisted, the interval in milliseconds when a checkpoint is forced on the head page
# Default is 1000, 0 for no periodic checkpoint.
#
# queue.checkpoint.interval: 1000
#
```
**pipeline.yml**
```auto
[root@logstash-helk ~]# cat /etc/logstash/pipelines.yml
# This file is where you define your pipelines. You can define multiple.
# For more information on multiple pipelines, see the documentation:
# https://www.elastic.co/guide/en/logstash/current/multiple-pipelines.html
- pipeline.id: winlogbeat
#pipeline.batch.size: 2000
#pipeline.workers: 6
path.config: "/usr/share/logstash/pipeline/winlogbeat/"
queue.type: persisted
- pipeline.id: packetbeat
#pipeline.batch.size: 2000
#pipeline.workers: 6
path.config: "/usr/share/logstash/pipeline/packetbeat/"
queue.type: persisted
- pipeline.id: pfsense
#pipeline.batch.size: 2000
#pipeline.workers: 6
path.config: "/usr/share/logstash/pipeline/pfsense/"
queue.type: persisted
- pipeline.id: vpn
#pipeline.batch.size: 2000
# #pipeline.workers: 6
path.config: "/usr/share/logstash/pipeline/vpn/"
queue.type: persisted
```
Basically we want to use persistent queue what configuration do we need to configure.We are using by default configutration.We dont know page capacity.

Did you read [Persistent queues (PQ) | Logstash Reference [7.14] | Elastic](https://www.elastic.co/guide/en/logstash/7.14/persistent-queues.html#configuring-persistent-queues)?

yes but we are using by default settings we just enable `queue.type: persisted`.

Then I'd just use the defaults, unless there are other issues that you are seeing.

ya i agree with you..but we dont know what value can we provide in queue.page\_capacity.

Well, from the docs, emphasis mine;
> - `queue.page_capacity` : The maximum size of a queue page in bytes. The queue data consists of append-only files called "pages". The default size is 64mb. **Changing this value is unlikely to have performance benefits.**
