FileNotFoundError (/system/etc/mtab) on Android (termux)

[stephengmatthews]

I installed glances according to the README on Android (7) under termux. When I run glances, it returns:

Traceback (most recent call last):
  File "/data/data/com.termux/files/usr/bin/glances", line 11, in <module>

FileNotFoundError: [Errno 2] No such file or directory: '/system/etc/mtab'

Is there any other information I can provide?

Can you try to disable the fs plugin:

glances --disable-plugin fs

[stephengmatthews]

Thanks for your help. I tried it and got this response. ``` $ glances --disable-plugin fs Traceback (most recent call last): File "/data/data/com.termux/files/usr/bin/glances", line 11, in <module> load_entry_point('Glances==3.0.2', 'console_scripts', 'glances')() File "/data/data/com.termux/files/usr/lib/python3.7/site-packages/glances/__init__.py", line 140, in main start(config=config, args=args) File "/data/data/com.termux/files/usr/lib/python3.7/site-packages/glances/__init__.py", line 106, in start mode = GlancesMode(config=config, args=args) File "/data/data/com.termux/files/usr/lib/python3.7/site-packages/glances/standalone.py", line 73, in __init__ self.stats.update() File "/data/data/com.termux/files/usr/lib/python3.7/site-packages/glances/stats.py", line 222, in update self._plugins[p].update() File "/data/data/com.termux/files/usr/lib/python3.7/site-packages/glances/plugins/glances_processcount.py", line 71, in update glances_processes.update() File "/data/data/com.termux/files/usr/lib/python3.7/site-packages/glances/processes.py", line 247, in update ad_value=None) File "/data/data/com.termux/files/usr/lib/python3.7/site-packages/glances/processes.py", line 246, in <listcomp> self.processlist = [p.info for p in psutil.process_iter(attrs=standard_attrs, File "/data/data/com.termux/files/usr/lib/python3.7/site-packages/psutil/__init__.py", line 1434, in process_iter yield add(pid) File "/data/data/com.termux/files/usr/lib/python3.7/site-packages/psutil/__init__.py", line 1416, in add proc.info = proc.as_dict(attrs=attrs, ad_value=ad_value) File "/data/data/com.termux/files/usr/lib/python3.7/site-packages/psutil/__init__.py", line 525, in as_dict ret = meth() File "/data/data/com.termux/files/usr/lib/python3.7/site-packages/psutil/__init__.py", line 749, in io_counters return self._proc.io_counters() File "/data/data/com.termux/files/usr/lib/python3.7/site-packages/psutil/_pslinux.py", line 1677, in io_counters "too old?)" % self.pid) NotImplementedError: couldn't find /proc/1546/io (kernel too old?) ```

Strange...

@giampaolo Any idea ? Did you test PsUtil with the latest Android version ?

[giampaolo]

Does /etc/mtab exist? It's weird it looks for /system/etc/mtab.

NotImplementedError: couldn't find /proc/1546/io (kernel too old?)

As for this one, psutil should probably avoid to expose Process.io_counters() method in case this is not available. I'll file a ticket.

```/etc/mtab``` does not exist.

I close this issue.

Please track the PsUtil issue here: giampaolo/psutil#1357

I still get the same issue (mtab not found), even though that PsUtil issue is already closed.
