i'm trying to use ELK "Elasticsearch , logstash and kibana" to monitor apache and nginx logs
and centralize logs into kibana.
now I have got logs of apache into logstash and kibana so,
what should i do to get ngnix logs too ??
Thanks.
An exact answer depends on
- your exact configuration and
- whether your Apache logs and Nginx logs look the same (i.e. if they can be parsed with the same filter).
Ok thanks @magnusbaeck but what about if there are multiple servers i want to monitor and the ELK into another server?
what should i do to monitor all servers "different machines" into a single ELK ?
Install Filebeat on all machines with logs and get them shipped to the machine where you want to run Logstash.

@magnusbaeck only filebeat or filebeat with logstash too ??
That's up to you. I prefer using Filebeat and Logstash together since Logstash has more extensive filtering abilities.

Really thanks alot @magnusbaeck
Is kibana can monitor apache request number , active workers and idle workers ?? if yse could you tell me how to make it into kibana ?
Kibana can monitor any data you throw at it. I don't think there's anything built-in for what you're looking for. but check out Metricbeat and its modules.

###################### Metricbeat Configuration Example #######################
This file is an example configuration file highlighting only the most common
options. The metricbeat.reference.yml file from the same directory contains all the
supported options with more comments. You can use it as a reference.
You can find the full configuration reference here:
https://www.elastic.co/guide/en/beats/metricbeat/index.html
#========================== Modules configuration ============================
metricbeat.config.modules:
-
module: system
metricsets:- cpu
- filesystem
- memory
- network
- process
enabled: true
period: 10s
processes: ['.*']
cpu_ticks: false
-
module: apache
metricsets: ["status"]
enabled: true
period: 1s
hosts: ["my_host"]Glob pattern for configuration loading
path: ${path.config}/modules.d/*.yml
Set to true to enable config reloading
reload.enabled: false
Period on which files under path should be checked for changes
#reload.period: 10s
#==================== Elasticsearch template setting ==========================
setup.template.settings:
index.number_of_shards: 1
index.codec: best_compression
#_source.enabled: false
#================================ General =====================================
The name of the shipper that publishes the network data. It can be used to group
all the transactions sent by a single shipper in the web interface.
#name:
The tags of the shipper are included in their own field with each
transaction published.
#tags: ["service-X", "web-tier"]
Optional fields that you can specify to add additional information to the
output.
#fields:
env: staging
#============================== Dashboards =====================================
These settings control loading the sample dashboards to the Kibana index. Loading
the dashboards is disabled by default and can be enabled either by setting the
options here, or by using the -setup CLI flag or the setup command.
#setup.dashboards.enabled: false
The URL from where to download the dashboards archive. By default this URL
has a value which is computed based on the Beat name and version. For released
versions, this URL points to the dashboard archive on the artifacts.elastic.co
website.
#setup.dashboards.url:
#============================== Kibana =====================================
Starting with Beats version 6.0.0, the dashboards are loaded via the Kibana API.
This requires a Kibana endpoint configuration.
setup.kibana:
host: "http://myhost:5601"
Kibana Host
Scheme and port can be left out and will be set to the default (http and 5601)
In case you specify and additional path, the scheme is required: http://localhost:5601/path
IPv6 addresses should always be defined as: https://[2001:db8::1]:5601
#host: "localhost:5601"
#============================= Elastic Cloud ==================================
These settings simplify using metricbeat with the Elastic Cloud (https://cloud.elastic.co/).
The cloud.id setting overwrites the output.elasticsearch.hosts and
setup.kibana.host options.
You can find the cloud.id in the Elastic Cloud web UI.
#cloud.id:
The cloud.auth setting overwrites the output.elasticsearch.username and
output.elasticsearch.password settings. The format is <user>:<pass>.
#cloud.auth:
#================================ Outputs =====================================
Configure what output to use when sending the data collected by the beat.
#-------------------------- Elasticsearch output ------------------------------
output.elasticsearch:
Array of hosts to connect to.
hosts: ["localhost:9200"]
Optional protocol and basic auth credentials.
#protocol: "https"
#username: "elastic"
#password: "changeme"
#----------------------------- Logstash output --------------------------------
#output.logstash:
The Logstash hosts
#hosts: ["localhost:5044"]
Optional SSL. By default is off.
List of root certificates for HTTPS server verifications
#ssl.certificate_authorities: ["/etc/pki/root/ca.pem"]
Certificate for SSL client authentication
#ssl.certificate: "/etc/pki/client/cert.pem"
Client Certificate Key
#ssl.key: "/etc/pki/client/cert.key"
#================================ Logging =====================================
Sets log level. The default log level is info.
Available log levels are: error, warning, info, debug
#logging.level: debug
At debug level, you can selectively enable logging only for some components.
To enable all selectors use ["*"]. Examples of other selectors are "beat",
"publish", "service".
#logging.selectors: ["*"]
#============================== Xpack Monitoring ===============================
metricbeat can export internal metrics to a central Elasticsearch monitoring
cluster. This requires xpack monitoring to be enabled in Elasticsearch. The
reporting is disabled by default.
Set to true to enable the monitoring reporter.
#xpack.monitoring.enabled: false
Uncomment to send the metrics to Elasticsearch. Most settings from the
Elasticsearch output are accepted here as well. Any setting that is not set is
automatically inherited from the Elasticsearch output configuration, so if you
have the Elasticsearch output configured, you can simply uncomment the
following line.
#xpack.monitoring.elasticsearch:
The Metricbeat logs probably contain clues, especially if you crank up the loglevel. If that doesn't help, ask in the Beats category.
