Charlie Sharpsteen created an issue   Puppet / PUP-7136 Allow lookup calls to be traced on a per-node basis Issue Type: New Feature Assignee: Unassigned Created: 2017/01/26 11:43 AM Priority: Normal Reporter: Charlie Sharpsteen Currently, one of the best tools for debugging a hiera() or lookup() call that isn't quite turning out right is to enable DEBUG level logging on the puppet server in order to get a trace of the files that were consulted when looking for a particular value: 2017-01-26 18:25:56,037 DEBUG [qtp137565235-68] [puppetserver] Puppet hiera(): Looking up profile::rabbitmq::cluster_nodes in YAML backend 2017-01-26 18:25:56,038 DEBUG [qtp137565235-68] [puppetserver] Puppet hiera(): Looking for data source nodes/test.cert 2017-01-26 18:25:56,038 DEBUG [qtp137565235-68] [puppetserver] Puppet hiera(): Cannot find datafile hieradata/nodes/test.cert.yaml, skipping 2017-01-26 18:25:56,038 DEBUG [qtp137565235-68] [puppetserver] Puppet hiera(): Looking for data source st02/rabbitmq 2017-01-26 18:25:56,038 DEBUG [qtp137565235-68] [puppetserver] Puppet hiera(): Cannot find datafile hieradata/st02/rabbitmq.yaml, skipping 2017-01-26 18:25:56,038 DEBUG [qtp137565235-68] [puppetserver] Puppet hiera(): Looking for data source st02 2017-01-26 18:25:56,039 DEBUG [qtp137565235-68] [puppetserver] Puppet hiera(): Cannot find datafile hieradata/st02.yaml, skipping 2017-01-26 18:25:56,039 DEBUG [qtp137565235-68] [puppetserver] Puppet hiera(): Looking for data source role/rabbitmq 2017-01-26 18:25:56,039 DEBUG [qtp137565235-68] [puppetserver] Puppet hiera(): Cannot find datafile hieradata/role/rabbitmq.yaml, skipping 2017-01-26 18:25:56,039 DEBUG [qtp137565235-68] [puppetserver] Puppet hiera(): Looking for data source common 2017-01-26 18:25:56,039 DEBUG [qtp137565235-68] [puppetserver] Puppet hiera(): Cannot find datafile hieradata/common.yaml, skipping 2017-01-26 18:25:56,044 ERROR [qtp137565235-68] [puppetserver] Puppet Evaluation Error: Error while evaluating a Function Call, Could not find data item profile::rabbitmq::cluster_nodes in any Hiera data file and no default supplied at /etc/puppetlabs/code/environments/st02/site/profile/manifests/rabbitmq/cluster.pp:2:30 on node test.cert This information can be compared against the configured hierarchy to deduce which values were in scope at the time that the lookup ran. There are however several downsides to this approach: Boosting the logs to DEBUG level requires manual edits to config files and a puppet server restart. DEBUG level output is generated for all agents, which absolutely kills the signal to noise ration of the logs. After debugging, the log level boost must be reverted via more manual edits and another restart. As a puppet operator, I would like the ability to enable lookup tracing on a per-agent basis so that I can quickly debug misbehaving lookups running on the server without disturbing the rest of my installation.
