1. 使用Logstash监控activemq-artemis的日志，通过Elasticsearch进行搜索和过滤，配置Kibana进行可视化展示。同时，可以通过Logstash的output插件发送邮件或者短信进行警报。

下面为Logstash的配置文件示例：

input {
  file {
    path => "/path/to/activemq-artemis.log"
    start_position => "beginning"
    sincedb_path => "/dev/null"
    ignore_older => 0
  }
}
 
filter {
  grok {
    match => { "message" => "%{DATESTAMP:timestamp} %{LOGLEVEL:log_level} (?(.*)) - (?(.*))" }
    add_tag => [ "monitored_log" ]
  }
}

output {
  elasticsearch {
    hosts => [ "localhost:9200" ]
    action => "index"
    index => "activemq-artemis-%{+YYYY.MM.dd}"
  }
  if "monitored_log" in [tags] {
    stdout {
      codec => rubydebug
    }
    email {
      from => "log_monitor@example.com"
      to => "admin@example.com"
      subject => "Log monitor alert"
      via => "smtp"
      body => "Logstash has detected an error in activemq-artemis log. Please check the logs for more details."
      htmlbody => "
 Logstash has detected an error in activemq-artemis log. Please check the logs for more details. 
"
      options => {
        address => "mail.smtp.server"
        port => "25"
      }
    }
  }
}

2. 使用Prometheus和Grafana监控activemq-artemis的日志，并设置相应的警报规则。Prometheus可以通过日志监控插件来监控日志文件，Grafana可以通过Prometheus数据源进行数据展示和报警通知。

下面为Prometheus的配置文件示例：

global:
  scrape_interval:     30s
  evaluation_interval:
