From 9decadfed2e90a595ef77ef06416b9071e59a61e Mon Sep 17 00:00:00 2001 From: Tamer Ahmed Date: Wed, 19 Aug 2020 19:27:59 -0700 Subject: [PATCH] [services] Fix Delay Start of SNMP And Telemetry (#5211) SNMP and Telemetry services are not critical to switch startup. They also cause fast-reboot not to meet timing requirements. In order to delay start those service are associated with systemd timer units, however when hostcfgd initiate service start, it start the service and not the timer. This PR fixes this issue by starting the timer associated with systemd unit. signed-off-by: Tamer Ahmed --- files/build_templates/init_cfg.json.j2 | 34 ++++++++++++++------------ files/image_config/hostcfgd/hostcfgd | 24 +++++++++--------- 2 files changed, 31 insertions(+), 27 deletions(-) diff --git a/files/build_templates/init_cfg.json.j2 b/files/build_templates/init_cfg.json.j2 index 2dc055833293..be1a66e1510b 100644 --- a/files/build_templates/init_cfg.json.j2 +++ b/files/build_templates/init_cfg.json.j2 @@ -17,25 +17,27 @@ {% endfor %} } }, -{%- set features = [("bgp", "enabled", "enabled"), - ("database", "enabled", "disabled"), - ("dhcp_relay", "enabled", "enabled"), - ("lldp", "enabled", "enabled"), - ("pmon", "enabled", "enabled"), - ("radv", "enabled", "enabled"), - ("snmp", "enabled", "enabled"), - ("swss", "enabled", "enabled"), - ("syncd", "enabled", "enabled"), - ("teamd", "enabled", "enabled")] %} -{%- if include_mgmt_framework == "y" %}{% do features.append(("mgmt-framework", "enabled", "enabled")) %}{% endif %} -{%- if include_nat == "y" %}{% do features.append(("nat", "disabled", "enabled")) %}{% endif %} -{%- if include_restapi == "y" %}{% do features.append(("restapi", "enabled", "enabled")) %}{% endif %} -{%- if include_sflow == "y" %}{% do features.append(("sflow", "disabled", "enabled")) %}{% endif %} -{%- if include_system_telemetry == "y" %}{% do features.append(("telemetry", "enabled", "enabled")) %}{% endif %} +{%- set features = [("bgp", "enabled", false, "enabled"), + ("database", "enabled", false, "disabled"), + ("dhcp_relay", "enabled", false, "enabled"), + ("lldp", "enabled", false, "enabled"), + ("pmon", "enabled", false, "enabled"), + ("radv", "enabled", false, "enabled"), + ("snmp", "enabled", true, "enabled"), + ("swss", "enabled", false, "enabled"), + ("syncd", "enabled", false, "enabled"), + ("teamd", "enabled", false, "enabled")] %} +{%- if include_mgmt_framework == "y" %}{% do features.append(("mgmt-framework", "enabled", false, "enabled")) %}{% endif %} +{%- if include_nat == "y" %}{% do features.append(("nat", "disabled", false, "enabled")) %}{% endif %} +{%- if include_restapi == "y" %}{% do features.append(("restapi", "enabled", false, "enabled")) %}{% endif %} +{%- if include_sflow == "y" %}{% do features.append(("sflow", "disabled", false, "enabled")) %}{% endif %} +{%- if include_system_telemetry == "y" %}{% do features.append(("telemetry", "enabled", true, "enabled")) %}{% endif %} "FEATURE": { -{%- for feature, state, autorestart in features %} +{# has_timer field if set, will start the feature systemd .timer unit instead of .service unit #} +{%- for feature, state, has_timer, autorestart in features %} "{{feature}}": { "state": "{{state}}", + "has_timer" : {{has_timer | lower()}}, "auto_restart": "{{autorestart}}", "high_mem_alert": "disabled" }{% if not loop.last %},{% endif -%} diff --git a/files/image_config/hostcfgd/hostcfgd b/files/image_config/hostcfgd/hostcfgd index 4fd47df60571..93a2cc03577c 100755 --- a/files/image_config/hostcfgd/hostcfgd +++ b/files/image_config/hostcfgd/hostcfgd @@ -41,12 +41,13 @@ def obfuscate(data): return data -def update_feature_state(feature_name, state): +def update_feature_state(feature_name, state, has_timer=False): + feature_suffix = "timer" if has_timer else "service" if state == "enabled": start_cmds = [] - start_cmds.append("sudo systemctl unmask {}.service".format(feature_name)) - start_cmds.append("sudo systemctl enable {}.service".format(feature_name)) - start_cmds.append("sudo systemctl start {}.service".format(feature_name)) + start_cmds.append("sudo systemctl unmask {}.{}".format(feature_name, feature_suffix)) + start_cmds.append("sudo systemctl enable {}.{}".format(feature_name, feature_suffix)) + start_cmds.append("sudo systemctl start {}.{}".format(feature_name, feature_suffix)) for cmd in start_cmds: syslog.syslog(syslog.LOG_INFO, "Running cmd: '{}'".format(cmd)) try: @@ -55,12 +56,12 @@ def update_feature_state(feature_name, state): syslog.syslog(syslog.LOG_ERR, "'{}' failed.
