Seems flag "-collector.textfile.directory" is in conflict with flag "-collectors.enabled". Is this expected? Or is there a way I can use those two flags at same time? Thank you.

Here is what I try and get:

I set "-collector.textfile.directory" to directory "/var/lib/node_exporter/textfile_collector" and will create a prom file named "gpfs_mount_time.prom" there and then my script will write metric "gpfs_mount_time" records into it. So if things go smoothly, I will get the metric stream when I curl the node exporter.

But when I run node_exporter with flags both "-collector.textfile.directory" and "-collectors.enabled", the textfile collector will not work. See below scenarioes:

Scenario 1: those two flags, -collector.textfile.directory and -collectors.enabled.

If I add those two flags, there will be no metric `gpfs_mount_time` collected.

[root@dev-repo scripts]# nohup /root/node_exporter -collector.textfile.directory /var/lib/node_exporter/textfile_collector -collectors.enabled nfs &

[root@dev-repo scripts]# curl http://localhost:9100/metrics -s -S | grep gpfs
[root@dev-repo scripts]#

Scenario 2: only flag, -collector.textfile.directory

the metric I wanna get can be collcted by node exporter if I just add flag `-collector.textfile.directory`.

[root@dev-repo scripts]# nohup /root/node_exporter -collector.textfile.directory /var/lib/node_exporter/textfile_collector &
[root@dev-repo scripts]#

[root@dev-repo scripts]# curl http://localhost:9100/metrics -s -S | grep gpfs
# HELP gpfs_mount_time Metric read from /var/lib/node_exporter/textfile_collector/gpfs_mount_time.prom
# TYPE gpfs_mount_time untyped
gpfs_mount_time{check_result_msg="Mount timeout",gpfs_node="node1"} 1

[root@dev-repo scripts]#

System and software info

[root@dev-repo scripts]# /root/node_exporter --version
node_exporter, version 0.14.0-rc.1 (branch: master, revision: 6fa6f476c71ca71c0bc4c20713b7082452b58d9f)

Additional info

I downloaded the newest version of node_exporter and repeated the test above with the newest binary node_exporter and got the same result.

[root@dev-repo scripts]# ./node_exporter --version

You've only enabled the nfs collector, which means the textfile collector is disabled. You need to list all the collectors you want to run.

Hi Brian,
The documentation says textfile collector is enabled by default. Do we need to specify "textfile" collector or any other collector which is enabled by default if using -collectors.enabled?
