From 803077ef1cdac1dc7f0bc9224adbb0de45f6bffc Mon Sep 17 00:00:00 2001 From: Bas van Dijk Date: Mon, 18 Dec 2017 20:53:54 +0100 Subject: elk: add elasticsearch6, logstash6, kibana6 and the beats at v6.1.0 This change is backwards compatible since the ELK tools at version 5.x remain unchanged. The test suite now both tests ELK-5 and ELK-6. --- nixos/tests/elk.nix | 172 ++++++++++++++++++++++++++++------------------------ 1 file changed, 92 insertions(+), 80 deletions(-) (limited to 'nixos/tests') diff --git a/nixos/tests/elk.nix b/nixos/tests/elk.nix index 65ff1cac070b..ed656b3628b9 100644 --- a/nixos/tests/elk.nix +++ b/nixos/tests/elk.nix @@ -1,95 +1,107 @@ -# Test the ELK stack: Elasticsearch, Logstash and Kibana. - -import ./make-test.nix ({ pkgs, ...} : +{ system ? builtins.currentSystem }: +with import ../lib/testing.nix { inherit system; }; +with pkgs.lib; let esUrl = "http://localhost:9200"; -in { - name = "ELK"; - meta = with pkgs.stdenv.lib.maintainers; { - maintainers = [ eelco chaoflow offline basvandijk ]; - }; - nodes = { - one = - { config, pkgs, ... }: { - # Not giving the machine at least 2060MB results in elasticsearch failing with the following error: - # - # OpenJDK 64-Bit Server VM warning: - # INFO: os::commit_memory(0x0000000085330000, 2060255232, 0) - # failed; error='Cannot allocate memory' (errno=12) - # - # There is insufficient memory for the Java Runtime Environment to continue. - # Native memory allocation (mmap) failed to map 2060255232 bytes for committing reserved memory. - # - # When setting this to 2500 I got "Kernel panic - not syncing: Out of - # memory: compulsory panic_on_oom is enabled" so lets give it even a - # bit more room: - virtualisation.memorySize = 3000; + mkElkTest = name : elk : makeTest { + inherit name; + meta = with pkgs.stdenv.lib.maintainers; { + maintainers = [ eelco chaoflow offline basvandijk ]; + }; + nodes = { + one = + { config, pkgs, ... }: { + # Not giving the machine at least 2060MB results in elasticsearch failing with the following error: + # + # OpenJDK 64-Bit Server VM warning: + # INFO: os::commit_memory(0x0000000085330000, 2060255232, 0) + # failed; error='Cannot allocate memory' (errno=12) + # + # There is insufficient memory for the Java Runtime Environment to continue. + # Native memory allocation (mmap) failed to map 2060255232 bytes for committing reserved memory. + # + # When setting this to 2500 I got "Kernel panic - not syncing: Out of + # memory: compulsory panic_on_oom is enabled" so lets give it even a + # bit more room: + virtualisation.memorySize = 3000; - # For querying JSON objects returned from elasticsearch and kibana. - environment.systemPackages = [ pkgs.jq ]; + # For querying JSON objects returned from elasticsearch and kibana. + environment.systemPackages = [ pkgs.jq ]; - services = { - logstash = { - enable = true; - package = pkgs.logstash5; - inputConfig = '' - exec { command => "echo -n flowers" interval => 1 type => "test" } - exec { command => "echo -n dragons" interval => 1 type => "test" } - ''; - filterConfig = '' - if [message] =~ /dragons/ { - drop {} - } - ''; - outputConfig = '' - file { - path => "/tmp/logstash.out" - codec => line { format => "%{message}" } - } - elasticsearch { - hosts => [ "${esUrl}" ] - } - ''; - }; + services = { + logstash = { + enable = true; + package = elk.logstash; + inputConfig = '' + exec { command => "echo -n flowers" interval => 1 type => "test" } + exec { command => "echo -n dragons" interval => 1 type => "test" } + ''; + filterConfig = '' + if [message] =~ /dragons/ { + drop {} + } + ''; + outputConfig = '' + file { + path => "/tmp/logstash.out" + codec => line { format => "%{message}" } + } + elasticsearch { + hosts => [ "${esUrl}" ] + } + ''; + }; - elasticsearch = { - enable = true; - package = pkgs.elasticsearch5; - }; + elasticsearch = { + enable = true; + package = elk.elasticsearch; + }; - kibana = { - enable = true; - package = pkgs.kibana5; - elasticsearch.url = esUrl; + kibana = { + enable = true; + package = elk.kibana; + elasticsearch.url = esUrl; + }; }; }; - }; - }; + }; - testScript = '' - startAll; + testScript = '' + startAll; - $one->waitForUnit("elasticsearch.service"); + $one->waitForUnit("elasticsearch.service"); - # Continue as long as the status is not "red".
